How to become full stack developer in 2019? – [Salary and Skills]

As a beginner, we always think what does full stack developer means? How to become full stack developer? From more than 2 years of experience and after so much of research I am going to answer your questions so that after reading this you don’t need to ask anyone about this farther.

A Full-Stack Web Developer is someone who is able to work on both the front-end and back-end portions of an application. Someone is familiar with each layer. Front-end generally refers to the portion of an application the user will see or interact with, and the back-end is the part of the application that handles the logic, database interactions, user authentication, server configuration, etc.

Being a Full-Stack Developer doesn’t mean that you have necessarily mastered everything required to work with the front-end or back-end, but it means that you are able to work on both sides and understand what is going on when building an application.

Front-end development

Front-end web development is the practice of converting data to a graphical interface for the user to view and interact with data through digital interaction using HTML, CSS, and JavaScript.

 In a simple way, when your search in Google with any URL then it shows you that website. The visual structure that you see is the front-end of that website. But if you create an account in that website and log in how it is happening? Where is your data going? That is the back-end of a website. We will discuss it “Back-end Development” section.

A front-end developer creates a beautiful good looking website from scratch. They make it user-friendly and responsive for all devices so that we can use it from desktop, laptop, tab, and mobile. For that, they use HTML, CSS, JavaScript, Jquery, Bootstrap, Angular, React, Vue etc.

If you don’t know about all those then there is nothing to worry about. Because We will learn everything together in the later part. So stay with me and keep learning.

Back-end development

A back-end developer is a type of programmer who creates the logical back-end and core computational logic of a website, software or information system. The developer creates components and features that are indirectly accessed by a user through a front-end application or system.

The back end comprises three parts: the server, your database, any APIs, and a back-end web application, software written via server-side languages. The server is a powerful computer that runs the back-end software, the database houses your site’s data, and the software communicates between the two.

 For example, if a user is updating a profile on a networking site, the server-side scripts will gather the information the user enters, the application will process it on the server, then interact with the database to update that information there.

Most popular server-side languages are PHP, Python, Ruby, C#, C++, and Java. There are also some server-side frameworks like Ruby and Rails, ASP.NET, Django and Node.js

If you don’t know what is framework then let me clear it first. A framework is a special kind of program that helps you to create your own web application very easily. A framework is designed to support the development of web applications including web services, web resources, and web APIs. You will find many inbuilt functionalities within a framework.

What does a Backend Developer Do?

Some of the things taken care of by backend developers include:

  • Writing server-side code
  • Writing code to interact with a database
  • Ensuring that the server-side code is secure and free of vulnerabilities
  • Ensuring that the server-side code is optimized enough to handle large volumes of traffic
  • Deploying the code online so that other people can use your service

Backend developers may work with other kinds of developers on a single project since the skill set required to complete an app or a web service is not limited to backend development.

Technical Skills of Front-end Developer

You should not necessarily become a master in each technology if you concentrate on both back-end and front-end. But what really matters is your ability and passion to understand everything that’s going on and make it work. This is a list of things to learn if you’re a technician or things to ask for if you’re a business owner.

Being a developer we always ask about best programming languages that have a good future. You can read about the top 10 programming languages. Click the link below and take a look.

HTML and CSS are two fundamentals, which you meet first at the very beginning of any programming course. It works this way because thanks to HTML you can add materials to a web page, and CSS helps to give it a certain style.

If you want to be a full stack developer You have to start your journey with HTML and CSS. Almost every single program, whether online or in-person, that is teaching you how to be a web developer will start with HTML and CSS because they are the building blocks of the web. Simply put, HTML allows you to add content to a website and CSS is what allows you to style your content.

For example, think about human body structure. You will find skeleton made up with bones. In a website, HTML works to create the skeleton of that website. There are some HTML tags that are used to do so. Now if you add skin to that skeleton than you will see a good looking body. Here comes CSS. After creating a website skeleton using HTML you will use CSS to give a good outlook.

We can use many tags to create a website. For example, we can create a heading for an article using a <h1> tag. This is HTML. Now you can give any color and font you want to this heading using CSS. That’s how HTML and CSS work together. I will create an HTML and CSS complete course totally for free. That will help you to learn very easily.

2.JavaScript & Jquery:

JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animated images, and pretty much everything else. It is a cross-platform, object-oriented scripting language used to make web pages interactive.

For example, the Human body is made of skeleton and skin. This gives a good looking structure. You also perform different kinds of function. Like you see things by our eyes, we hear the sound, we can smell. We also can use functionalities on our website. To do so we use JavaScript.

JavaScript contains a standard library of objects, such as Array, Date, and Math, and a core set of language elements such as operators, control structures, and statements. Core JavaScript can be extended for a variety of purposes by supplementing it with additional objects; for example:

  • Client-side JavaScript extends the core language by supplying objects to control a browser and it’s Document Object Model (DOM). For example, client-side extensions allow an application to place elements on an HTML form and respond to user events such as mouse clicks, form input, and page navigation.
  • Server-side JavaScript extends the core language by supplying objects relevant to running JavaScript on a server. For example, server-side extensions allow an application to communicate with a database, provide continuity of information from one invocation to another of the application, or perform file manipulations on a server.

The JavaScript is executed by the browser’s JavaScript engine after the HTML and CSS have been assembled and put together into a web page. This ensures that the structure and style of the page are already in place by the time the JavaScript starts to run.

Jquery is the most popular JavaScript library to website development. It a collection of JavaScript functions. You can use them very easily to create your necessary functions.  It is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. Before going to discuss why you should use jquery I want to clear the confusion between framework and library. You have heard these two words many times.

What is the difference between framework and library?

library vs framework

The key difference between a library and a framework is “Inversion of Control”. When you call a method from a library, you are in control. But with a framework, the control is inverted: the framework calls you.

A library is a piece of code that provides more freedom and control in your work. While using a library you have full control of your design and functionalities. A library will usually focus on a single piece of functionality, which you access through an API. That means fewer rules.

A framework is a piece of code which dictates the architecture your project will follow. Once you choose a framework to work with, you have to follow the framework’s code and design methodologies. The framework will provide you with hooks and callbacks so that you build on it – it will then call your plugged-in code whenever it wishes, a phenomenon called Inversion of Control. In a framework, you have to follow more rules given by the framework you choose.

Why should you use JQuery?

jQuery is very compact and well-written JavaScript code that increases the productivity of the developer by enabling them to achieve critical UI functionality by writing a very small amount of code.

  • JQuery helps to improve the performance of the application
  • It helps to develop most browser compatible web page
  • It is fast
  •  jQuery can be extended to implement customized behavior
  • It helps to implement UI related critical functionality without writing hundreds of lines of codes

Other advantages of jQuery are:

  • No need to learn fresh new syntaxes to use jQuery, knowing simple JavaScript syntax is enough
  • Simple and cleaner code, no need to write several lines of codes to achieve complex functionality


Bootstrap is an open-source CSS framework that combines HTML, CSS, and JavaScript code to help developers build web applications. It can be used for desktop and mobile development. Bootstrap will help you design websites faster and easier. It includes HTML and CSS based design templates for typography, forms, buttons, tables, navigation, models, image carousels, etc. It also gives you support for JavaScript plugins.

Why I use Bootstrap?

  • It is very easy to use.
  • It helps to make your website responsive and mobile friendly very easily.
  • It will increase the speed of development.
  • Ensure cross-browser compatibility.
  • Easily customizable. The Bootstrap can be customized as per the designs of your project.
  • It provides packaged JavaScript components.
  • Add consistency to design and code between projects and between developers.

There are many CSS frameworks that are used to create the UI user interface of a website other than bootstrap. Like, foundation, materialize, semantic UI, Bulma.

4. Responsive Layout

Basically, responsive web design is all about making a website automatically resizable for different devices like desktop, table, and mobile.

Number of mobile users is increasing rapidly. So, it becomes obvious to optimize a website for both tablet and mobile devices.

If you make your website responsive then it will fit in different screen size. You can also change your website layout according to screen size. That means the layout of your website in desktop and in mobile devices will be different.

5. Front-end Frameworks

There are several frontend frameworks available based on JavaScript. Most popular ones are React, Vue, and Angular.

Nowadays, without knowing a frontend framework you can not work as a frontend developer. These frameworks work almost the same way with some basic difference.

React is the most popular among them created by Facebook. Many big companies are using this framework. If you are interested in getting job, this might be good choice for you.

Next comes Vue. It is the easiest frontend framework I know. As a beginner, you might learn Vue.js. It’s popularity and demand are raising day by day.

Angular uses typescript as its language. Then it compiles typescript to JavaScript. If you want to learn this framework then first you need to learn typescript. I would suggest you choose from reacting or Vue.

6.Chrome developer tools:

Chrome developer tools for developers

Chrome DevTools are a developer’s best friend. With the explosion of Javascript frameworks, it’s more important than ever that you have the ability to work with your code live in the browser. Though DevTools are incredibly powerful we’re, only going to cover a small subset of their abilities in this post.

DISCLAIMER: In order to get the most out of this, you should be using Chrome.

The DevTools panel allows you to interact with the HTML, CSS, and Javascript running on just about any page on the internet. They’re great for messing around, but their real purpose is to save developers time and mental anguish. DevTools save you time by allowing you to manipulate your code in the browser, allowing you to quickly debug styling issues and play with different ideas.

In order to use DevTools, you’ll need to right click somewhere on the page and select “inspect element”. This will bring up an entirely new pane in your browser showing all the assets used on that page.

7.Version control:

A component of software configuration management, version control, also known as revision control or source control, is the management of changes to documents, computer programs, large websites, and other collections of information.

What is Git?

Git is a version control system that allows developers working on a team to keep track of all the changes being made to a codebase. It’s important to know a few important things related to Git so that you understand how to properly get the latest code that you’ve missed, update parts of the code, make fixes, and change other people’s code without breaking things.

8. NPM, Webpack, Babel, Sass

Next thing a frontend developer should know about is NPM. It is a node.js package manager. It helps with installing various packages and resolving their various dependencies. You will know about this when you learn node.js

There are also some other technologies like webpack, Babel and Sass. Sass is the CSS preprocessor. It allows developers to write code in one language and then compile it into CSS. You are also able to use some features that CSS does not provide like variables, nesting, inheritance.


Although frontend developers don’t work with server request, still they should have basic knowledge about http request. Backend developers always work on server requests, http or https protocols. They also should have skills handling data from JSON files and APIs. Frontend development is not that simple like it was a few years back. Therefore, you have to learn these technologies.

10. Design skills

Sometimes design skills is also important for frontend developers. Big companies usually heir designs for their projects. Otherwise, basic use of photoshop, design knowledge or knowing color combination might help you.

So, this is almost everything you should know to work as a frontend developer. It might look a lot but nowadays websites are built with many modern features. Now, let’s see the technical skills for a backend developer.

Technical Skills of a Back-end Developer

This is the list of technologies that every back-enc developer should have.

1. Server-side Languages

Once you feel you’ve gotten a good grasp on HTML/CSS and JavaScript, you’ll want to move on to a back-end language that will handle things like database operations, user authentication, and application logic.

There are many back-end languages. Like Node.js, PHP, Python, Ruby, C#, C++, and Java.  We have discussed this in the back-end development section. You can start will any of them.

If you want to start as a freelancer and full stack developer, I will suggest you start with PHP. There is a huge demand of PHP in different freelance marketplaces to work and earn a good amount of money.

If you want to work in big companies then you should start with Java or Python. To work in big companies you have to know 2 or 3 languages. Don’t worry after learning one language, It will be very easy to learn about others. Because the basics are the same for all languages.

Node.js is a JavaScript runtime environment built on Chrome’s V8 JavaScript engine. Both your browser JavaScript and Node.js run on the V8 JavaScript runtime engine. This engine takes your JavaScript code and converts it into faster machine code.

If you use nodejs in your server-side then you don’t have to learn whole new language for your backend. You are able to use javascript in both client-side as well as server-side.

Python is a scripting language. Mainly python is used in AI, machine learning, data science. You can also use it in server-side. Other languages like c#, ruby, java these are also used for web development. But for website development nodejs or PHP would be the best choice.

2. Server-side frameworks

Learn a framework, after learning a language you should go for a back-end framework. I will suggest choose the framework related to your language that you know. If you know PHP then go for Laravel.

Framework provides readymade functions and features that you can use your projects. Different language has different frameworks. You must pick up a framework based on the language you are working on. It will abate your pain and accelerate your working speed.

I think the back-end frameworks which are trending are:

Nodejs – Express, Koa              

Python – Django, Flask

PHP – Laravel, Symphony


3.Databases and Storage:

A database (DB), in the most general sense, is an organized collection of data. More specifically, a database is an electronic system that allows data to be easily accessed, manipulated and updated.

Modern databases are managed using a database management system (DBMS). A database management system (DBMS) is a type of software that allows you to define, manipulate, retrieve and manage data stored in a database.

Software programmers are well acquainted with database concepts through relational databases like Oracle, SQL SERVER and MySQL, etc. Typically, a database structure stores data in a tabular format.

  • Understand the benefits of relational data, e.g. SQL.
  • Learn about NoSQL databases, e.g. MongoDB.
  • Understand which would be better in certain situations.
  • Know how to connect a database with your chosen back-end language (e.g. Node.js + MongoDB).
  • Understand the benefits of in-memory data stores like Redis or Memcached.
  • Web storage to store sessions, cookies, and cached data in the browser.
  • Scaling databases, ACID, and ORM (all optional).


HTTP is a stateless application protocol on the Internet — it’s what allows clients to communicate with servers (e.g. your JavaScript code can make an AJAX request to some back-end code you have running on a server which will happen via HTTP). Some important topics you should learn about are listed below:

  • What is REST and why is it important in regards to the HTTP protocol and web applications.
  • Best practices for designing a RESTful API. POST/GET requests.
  • Learning how to use Chrome DevTools can be extremely helpful.
  • What are the SSL Certificates?
  • HTTP/2 & SPDY (optional).
  • WebSockets, Web Workers, and Service Workers (all optional).

5.Web Application Architecture:

Web Application Architecture

Once you think you have a grasp on HTML/CSS, JavaScript, back-end programming, databases, and HTTP/REST, then comes the tricky part. At this point if you want to create a somewhat complex web application, you’ll need to know how to structure your code, how to separate your files, where to host your large media files, how to structure the data in your database, where to perform certain computational tasks (client-side vs server-side), and much more.

There are best practices that you can read about online on, but the best way to actually learn about application architecture is by working on a large application yourself that contains several moving parts — or even better, working on a team and together developing a somewhat large/complex application.

This is why, for example, someone with 7+ years of experience as a full stack developer may not necessarily know CSS or JavaScript better than someone with 2 years of experience, but over all of those years they’ve presumably worked with all sorts of different applications and websites and have learned how to architect and design applications to be most efficient and can see the “big picture” when it comes to development.

6. Security

Cyber security is very hot topic in recent time. I guess you have heard about hacking. Websites get hacked by some evil people. So as a backend developer must know how to provide security.

Like, protection from SQL injection, safe file upload, user input validation, hide the password. You can do all those by writing proper code.

Technical Skills of a Full Stack Developer

Skills for a full stack developer consists of frontend and backend developers’ skills sometimes some extra knowledge. The main challenge for a full stack developer is to handle client-side and server-side at the same time. They have to work on both sides.

Other than this, they may need to learn some important CMS – content management system like wordpress, drupal, ghost, keystone.

Among all of them, wordpress is the most popular CMS. If you are interested to become a freelancer then you must know how to work on wordpress. Because large portion of the web is using this CMS.


wordpress for full stack developer

WordPress is an online, open source website creation tool written in PHP. But in non-geek speak, it’s probably the easiest and most powerful blogging and website content management system (or CMS) in existence today. Every full stack developer must know how to use WordPress to work as a freelancer.

Going straight to the point, WordPress is simply a content management system (CMS). This wasn’t the case though some ten (10) years ago when WordPress was just a blogging platform. Today, besides blogging, you can use WordPress to build and run powerful websites of all demeanor.

Why Use WordPress?

  • WordPress is Easy to Use & Learn

Full stack developer salary

If I talk about the salary or how much money a developer could make then actually it depends. It depends on the area, country you belong to. Different country has different economy and demand.

A frontend and backend developer make almost same amount of money. A full stack developer might make slightly more. It also depends on developers’ experience. Big companies pay more money small companies pay less money. I hope you got my point.

There are a lot of ways of earning money for a full stack developer. Here is the list of how to make money as a full stack developer. But this is not all, there are many more.

  • Become a freelancer.
