What are Full Stack Developers?

 

Understanding the Different Types of Web Development

 

By Leila Kojouri

 

When it comes to software development, there’s no shortage of titles, surnames, and appropriations in the many job roles associated with the field.

 

Before we get into the details of full stack development, it’s best to take a look at the big picture, and understand a little bit about each primary role in software development.

 

Front end developers, for example, focus on the actual presentation of your website, and how the information is laid out in browsers and on mobile devices. 

 

Front End Developers

 

Essentially, front-end developers wish to ensure the best “look and feel” of your website.  In the digital battlefield, front-end workers are equipped with an arsenal in the HTML, CSS and JavaScript (the “scripting language”). With these languages, the developer can very efficiently manipulate content on a website to make it appealing and effective to the right audience(s).

 

Everything you see on a website, such as the layout, positioning of text and images, colors, fonts, buttons, and so on—are all factors that the front-end developer working in web applications must consider in their roles. The “user experience,” for example, is largely dictated by the works of the front-end developer. 

 

The main goal of a front-end developer is to provide the platform for visitors to interact with, a platform which provides and receives information. This means some developers will be well-versed in web design and using software such as Photoshop and Illustrator to create graphics and themed layouts.

 

Back End Developers

 

While front end developers concern themselves with all things visual, back end developers concentrate on the creation, flow, and management of data. Some of the processes most often associated with back end development involve creating, editing/updating and recollecting data.

 

Common scripting languages include PHP, Ruby, and Python. With these languages, a back-end developer can create algorithms and business logic to manipulate the data that was received in front-end development.

 

This means that a back-end developer must have the ability to write code, requited to receive the information input from the user – and saving it somewhere – like in a database. SQL is the language used for database management, which helps the developer interact with the database.

 

Full Stack Developers

 

Full stack web developers – good ones, anyway – seek to integrate the best of both worlds in front and back end development.

 

The phrase “full stack” quite literally means the full stack of technology that makes up a website – so the full stack developer is proficient in both front-end and back-end programming languages and frameworks, as well as in server, network and hosting environments.

 

Usually, most full-stack developers will have spent many years working in a variety of different roles to get to this breadth and depth of knowledge.

 

They also tend to be well-versed in both business logic and user experience, meaning they are  well-equipped to get hands on – but can also guide and consult on strategy, too. 

 

Summary

 

Given this dynamic ability to use the full spectrum of development skills, it’s no wonder full stack developers are in such high demand.

 

A full-stack developer has all the keys to the house – there is no door that you cannot open.

 

It provides an unparalleled freedom to simultaneously work on front-end and back-end development and evaluate the capabilities and potential of your website in real-time without having to wait for another developer to review if what you’re desiring is possible or not.

3 Recruitment Trends on the Rise

 

A few years back, slightly more than 50 percent of recruiters foresaw a candidate-driven job market. Today, 90 percent of recruiters are convinced that the candidates will play a crucial role in any hiring process and role. Let’s take a look at the shift in recruitment trends,  as well as the trends for recruitment in 2019 and beyond.

 

It’s also important to say that in mature markets, unemployment levels have hit their second-lowest point over the past four decades; simply pointing out that job candidates are the ones with the ball in their court.

 

According to a thorough research, “Come 2027, 60 percent of people in the work arenas would become independent professionals. The ever-changing technology is the power behind this shift, plus the new generation job seekers are reaching out more to flexibility as well as higher purpose in a career”.

 

Indeed, job candidates’ expectations are evolving and would definitely shake up things. Besides, a digitalized lifestyle is on the increase; for instance, in the tech sector hiring, candidates are ditching the traditional application process and are increasingly embracing a low-effort, one-click micro job site. Even for talent acquisition, the present generation is clamoring for new approaches.

 

Recruitment Trend #1: Recruitment Automation Tools

 

This is simply the use of software programs that work with new technologies to automate recruiting process. Although these automation tools for recruiting are not new, they are moving to advanced levels, beyond the regular Applicant Tracking System, as well as Recruitment Marketing Software. What people are going to witness more is a new trend that combines these job automation tools using a single platform.

 

These innovative recruitment tools are quite helpful in attracting, engaging and ultimately converting candidates. In addition, recruiters can use them to streamline, simplify as well as automate hiring process, resulting in a faster and increasingly efficient outcome.

 

So, companies and organizations that are reluctant to integrate recruitment technology and automation tools in their recruitment plan and processes stand the risk of losing the best talents to their rivals who are more forward-thinking and recruitment-tech oriented.

 

Recruitment Trend #2: Talent Sourcing

 

A must-imbibed recruitment strategy in 2019 and beyond is proactive talent sourcing. According to a LinkedIn research, job seekers make up only 36 percent of potential candidates.

 

But, over 90 percent of these people show interest in information related to new job opportunities.

 

Trend #3: Increased Use of Mobile Recruiting Apps

 

Also, the job recruiting arena will witness increase use of recruiting apps in 2019 and beyond. These are apps that recruiters can adopt in posting career opportunities, especially those optimized for smart devices such as smart phones and tablets.

 

Many forward-thinking organizations and recruiters are already integrating these apps in their recruitment processes and strategy, while others are sluggish to do so (to their own disadvantage).

 

In addition to mobile recruiting apps, social recruiting will also be on the increase. This is the use of social platforms as databases for talents, and also to achieve employer branding.

5 MicroServices Trends to Look Out For

 

Understanding emerging MicroServices trends in functionality, protocols, containers, data, and infra

 

Formerly, when using MicroServices, ever-present infra-related issues were problematic. Luckily, through the tremendous open source community, many of these problems have been dealt with head-on. Explore the highlights of 5 microservices trends to look out for in the near future.

 

1. No More Worries about Protocols

 

Burdensome uncertainty in protocol marked a popular trend in the realm of microservices. Should it be the regular HTTP? Why not the recently matured HTTP/2? Indeed, deciding the best protocol has become worrisome and tedious. However, new developments in protocol will likely eliminate this worrisome task. Why, you ask? There will be the rise of protocol agnostic platforms. So then, users are enabled to communicate with other protocols without intense translation middleware methodology. Additionally, it would in turn aid better connectivity of microservices. Finally, there will be more robust protocol combinations such as GRPC ->HTTP, HTTP->GRPC, and GraphQL->GRPC.

 

2. Not Just Functions but Features as a Service

 

Currently, there are numerous available APIs. It becomes easy to kick start functionality with the aid of helpers such as Firebase and services on AWS. When microservices are programmed in a key-based direction, they can act as a feature geared towards multiple applications. A typical example is the authentication of every API, called using an app id. This helps individuals to design really fascinating feature pools and make room for their easy cloud orchestration in an agnostic manner.

 

3. Container Driven CI/CD

 

Argo, as well as other projects, tends to treat containers like tasks. Even the version 1.6 of Kubernetes initially introduced initContainers as post tasks geared towards extra configuration. In 2019, adopting containerization to abstract CI and CD will be a major trend. It would be better to treat them as cron job, rather than hook them up in an infra. Also, they should be treated as occurrences resulting from an event firing via code, rather than getting them hooked up in an infra.

 

4. Microservices Shared Data/Contexts

 

When it comes to the pattern of building microservices, processes are becoming increasingly ‘loosely coupled’ as well as stern. There’s an emergence of several event-driven tools; typical examples include ‘Serverless’ Event Gateway. This pitches event-driven microservices.

Automated microservices can be enabled via listening to a hitch-free login event of a different microservice inside an application, without manually firing even one event. At the same time, it possesses the ability to control what gets to third party listeners. It’s time to treat today’s microservices with dependencies alongside communication.

 

5. Less or Zero Worry about Infra

 

Don’t worry anymore about infra, but focus on their application requirements. The Serverless style will become a focus this year, to enable easy environments to switch away from “always on”. Besides, there’s a need to support additional languages. There should be a possibility for using any language and making it serverless.

What are Instant Apps?

Understanding Instant Apps and The Lighter Mobile Experience

 

Instant Apps Are the Easy Way to Try Apps and Games Without Installation.  

 

What Are Instant Apps? 

 

An Instant app is a lighter version of a regular android app which gives users full access to the application features without having to install it on their device. In the realm of application development, trying the “lite”  version is beneficial to both the user and developers, because users don’t need to commit and developers can learn about users habits immediately after releasing their product. 

 

Instant apps usually work through a URL and provide users with the same ease and immediacy they get while surfing the web. As such, they have become a universal android solution with quite a lot of advantages both to the developer and the end user.

 

Why Instant Apps? 

 

Here are some features that make up instant apps:

 

Easy Access to User Base

 

A lot of times, users get overwhelmed with the many apps being advertised on social media, websites, promotional links, and videos. So, they find it hard to install as many as they would have wanted to, due to memory space and bandwidth issues. Instant apps solve this problem, as all they need to do is just click and enjoy the app.

 

Ease with Sharing and Distribution

 

Sharing apps can be quite tasking as users usually have to download and install another application just to share the app. Instant apps eliminate this problem as the app can now be shared by just sharing the link.

 

The “Trial” Privilege

 

The natural instinct of most users would be to take a peek to see how the app looks, feels and works, and perhaps play around a bit before making a download decision. The instant version of the app gives this privilege for free to the user. Check the app, appreciate its look and feel, see how it functions, and then make the choice.

 

User Retention 

 

Apps that have a web version tend to have better retention rates than apps that do not. This is because in the end, only interested users get to download and keep the actual app.

 

Increase Feedback

 

Developers may now get their much-needed feedback, as users are able to provide feedback based on their experience with the instant app.

 

How Instant Apps Work

 

It’s simple: Google Play receives a request for a URL matching the instant app from a device and sends the necessary code files to the device. This enables the app to run in the device. All users need to do to use this feature is to enable Instant Apps from settings.

 

How do I enable the instant app feature? 

 

1. Go to the Phone Settings menu.
2. Scroll down to the Personal category and tap Google.
3. Under the Services category, select Instant Apps.
4. Tap the toggle on the top-right of the screen.
5. Read through the Terms of Service and select “Yes” in agreement

 

Supported Versions:

 

Instant apps work with Android devices above Lollipop 5.0 and API level 21

 

Everyday Advantages of Instant Apps:

 

Easy/Quick Feature Access:

 

Actions such as making payments have never been easier with instant apps.

 

Timely User Acquisition:

 

A new user who desperately needs a cab to get out from the rain doesn’t need to wait for the Uber app to download over their data plan. Using an Instant app makes it faster, and gets users what they need immediately.

 

Better E-commerce:

 

They give further information about a product faster than the regular app.

3 Ways to Customize DevOps 

 

In 2019 and beyond, DevOps will be increasingly customizable via cloud & containers, machine learning/artificial intelligence, and security

 

When it comes to the software development life cycle (SDLC), the ability to edit a process, customize an inherited process, and track the number of customizations is considered sacred. With DevOps, the SDLC is especially manageable, partly due to the emphasis on teamwork, collaboration, and synchronization between business units. 

 

The ever-growing popularity of DevOps means an increased fine-tuning of the overall DevOps process. This customization of DevOps is already gaining traction, and we can expect to see more in the years ahead. The DevOps community is already finding some trending behavior, such as capitalizing on the ability to leave feedback, or soliciting feedback directly on github. Process models for projects are discussed at length on some user boards, with members of the projects exchanging best practices and user stories.

 

When integrated properly, DevOps has the potential help businesses attain hugly competitive advantages in the marketplace. With that said, take a look at 3 innovative ways units are customizing their DevOps to get the most out of their daily grind.

 

#1: Cloud and Containers

 

Making life easier for the end-user begins with the developers in software delivery. By focusing on cloud and container based solutions from ideation to execution – or in the case of software delivery, from the testing phase to production, developers can make room for increased self-service, which is very popular among end-users. 

 

What’s more, developers used to spend hours creating painstaking, elaborate scripts detailing various tasks, tedious to-do lists – creating models to describe each and every one of their work processes. Now, with the introduction of self-service capabilities, these laborious, pre-emptive efforts may be curtailed or done away with entirely, simplifying the process.

 

An example of this simplicity exists in the execution of commands. When trying to build a Kubernetes pipeline for instance, commands such as “get entire data set” ensure faster, smoother operations for teams involved in the SDLC; whereas previously, these commands were faulty or did not exist at all. 

 

#2: Machine Learning and Artificial Intelligence

 

We can expect to see an increase in machine learning and artificial intelligence integration in tech trends for 2019. According to a DevOps strategist and expert, emerging DevOps operating systems merge concepts involving artificial intelligence and machine learning.

 

The focus predominately relies on next-level  predictive analytics, with efforts resulting in the production of authentic, valuable business deliverables.  Moreover, a focus on the best application of both Machine learning and artificial intelligence will become hot items in the near future – with 2020 being the year where they will likely shine.

 

Ultimately, machine learning and artificial intelligence will promote efficiency throughout every phase within the DevOps lifecycle. One may ask, could tasks be done faster? What are methods to reduce the cycle time in a pipeline, from inception to production? Now, assuming the pipeline lasts two days, if competitors offer same-day processing, you can see the difference in competitive advantage. Harnessing Machine Learning and AI will help curb the competition, by completing this process in just one single day or less, other than the typical two days.

 

#3: DevOps Security

 

Prioritizing security when it comes to DevOps is a trend we will definitely see gaining traction in 2019. The buzzword “DevSecOps” (Dev Security Ops) may become a household term in the coming years. 

 

The time is nigh to stop the practice of adopting vulnerable frameworks susceptible to attack. Security integration will become part of the lifecycle upon inception, rather than an afterthought – as DevSecOps sees it’s way into the pipeline upon the beginning of development.

 

Prior to the production phase, security teams should reinforce efforts in checking and validating code to maximize safety and prevent problematic encounters.

6 E-Commerce Personalization Trends

 

According to research conducted by BigCommerce, 80% of people in the U.S. make purchases online at least once a month. While the majority of people shop on large marketplace websites like Amazon, roughly 30 to 40% also purchase from online retailers like web stores, independent boutiques, and category-specific e-retailers. This year we’ll see several e-commerce trends emerge with the potential to transform how we shop and communicate with online stores. 

 

1) Mobile first 

In 2016, mobile commerce sales accounted for over $25 billion in sales, an increase of more than 25%. This figure is predicted to continue to increase, reaching over $30 billion in 2017, and $42 billion by 2020. Mobile traffic has overtaken the desktop. Google is working on a new, mobile-first web index and marketing strategy. According to these trends, it’s critical to business to put mobile first, rather than simply optimizing for mobile.

 

2) Digital payments

Mobile payments are on the rise as smartphone users adjust to the convenience of contactless payments. Starbucks was an innovator in mobile payments, becoming one of the first to offer products based on an online payment model. In 2016, an increasing number of customers adopted digital payment methods, using their phones, cards and even watches to complete contactless payments. PureNet predicts that every customer will expect to be able to complete their transaction using a digital wallet in real time.

 

3) Personalization and Customization

The amount of data available increasingly allows content, ads, and products to be shown to the right people at the right time, across the web and social networks. The continuing sophistication of personalized recommendations will be trending for ecommerce this year. Retailers will embrace personalized experiences – even using e-mail marketing to cater personalized emails to consumers, rendering unique customer experiences. and Artificial Intelligence by starting to collect behavioral data like browsing history, geo location, and social media from website visitors and developing highly targeted campaigns based on customer segments and previous online experiences.

 

4) Fast delivery

Ecommerce delivery timescales have reduced drastically and become much faster, boosting customer relationships with ecommerce sites. Delivery and returns have always been one of the pain points of the online shopping experience, but improvements in technology have improved delivery significantly. PureNet predicts same day delivery will continue to rise in 2017, and more ecommerce integration with drop-off point providers such as Doddle.

 

5) Technology

Technology will continue to play a greater role in automating the retail experience. With the help of the latest technology, sales people will be able to focus on building relationships with customers to increase sales. In order to stay competitive, businesses must invest in high-performing ecommerce solutions. Providers such as Charter Global, apply leading technology tools to deliver customized ecommerce solutions to mid-size and Fortune 1000 companies. Experienced providers offer expertise across multiple, proven Cloud-based ecommerce platforms such as SAP HANA, SAP Business One, Magento, PCI DSS, Spring MVC (Framework ), Magnolia CMS/ Blossom module, HTML5, CSS3, JQuery, and Struts.

 

6) Chatbots

Chatbots are AI-led automated messenger services that allow your customers to engage with your brand via instant messenger via machine learning. Over the last few years messaging apps have exploded in popularity, and thanks to ecommerce personalization, artificial intelligence technology has been adopted by many large retailers. This year will see these two trends combine to deliver a new way of shopping and communicating.

What is Usability?

So what exactly is “usability” with respect to software and application development? Usability means making products, systems, websites and web applications easier to use, matching them more closely to user needs and requirements. A website very often serves as the first impression to your customers – and you need to ensure it is a good one to keep them coming back. Good usability and user experience should capture the best possible human computer interaction.

 

A highly usable system doesn’t just offer benefits to the users, but to your business as well.

 

The primary benefits to users are that they can achieve their tasks easily and efficiently. This sounds simple, but the feeling of achievement that people get when they use a computer system without frustration should not be underestimated.You don’t want your users getting frustrated because they can’t navigate your site. Consider your website as the first impression your customers get, and you want that introduction to leave a pleasant memory, not a bitter one.

 

Components of Usability:

 

• Effective – Effectiveness is the completeness and accuracy with which users achieve specified goals.
• Efficient – Efficiency can be described as the speed in which users can complete the tasks for which they use the product.
• Error – The ultimate goal is a system which has no errors.
• Easy to Learn – How easy is it for users to accomplish basic tasks the first time they encounter the design?
• Satisfaction – How pleasant is it to use the design?

 

How to Improve Usability:

 

There are many methods for usability, but the most basic and useful is user testing.

 

User testing is different from focus groups, which are a poor way of evaluating design usability. Focus groups have a place in market research, but to evaluate interaction designs you must closely observe individual users as they perform tasks with the user interface. Listening to what people say is misleading: you have to watch what they actually do.

 

Usability’s Role in the Design Process:

 

Usability plays a role in each stage of the design process.

 

• Before starting the new design, test the old design to identify the good parts that you should keep or emphasize, and the bad parts that give users trouble.
• Conduct a field study to see how users behave in their natural habitat.
• Make paper prototypes of one or more new design ideas and test them. The less time you invest in these design ideas the better, because you’ll need to change them all based on the test results.
• Refine the design ideas that test best through multiple iterations, gradually moving from low-fidelity prototyping to high-fidelity representations that run on the computer. Test each iteration.
• Once you decide on and implement the final design, test it again. Subtle usability problems always creep in during implementation.

 

Usability Guidelines and Standards:

 

Usability guidelines and standards can be useful to provide ideas about usability issues, but they must be assessed to determine whether they are relevant to the users and context.

 

As an example, a common website guideline is that all content should be available within three clicks. The intent of this guideline is good – it highlights that people should not have to click endlessly for information. However, there are situations where it is not applicable. Large sites or sites with information designed to present increasingly detailed pages may not meet the guideline, but may be very usable for the intended audience.

 

Guidelines and standards are best used to identify the most obvious usability problems and fix them before a usability test is conducted.
