What Does a Web Developer Do?

A web developer creates websites using various programming languages. His responsibilities include the design of web pages and the development of the site’s functionality to meet the needs of users.

Sometimes after the project is finished, a web developer can maintain the website’s performance, make updates, and check for technical problems.

Web development covers a wide range of areas, and it is divided into three specializations:

  1. Front-end web developer 
  2. Back-end web developer
  3. Full Stack Web Developer 

Key Skills and Knowledge Front-End Developer Needs

The most in-demand skills include popular programming languages and other software-oriented competencies, such as a financial services software program.


The first skill one needs to master to be a web developer is programming. There are many languages ​​for each objective, but you need to know some of them to code a web page. 

You can choose the ones you like the most for their simplicity or complexity of learning, universal use, web development standards, trends, recommendations, etc. For example, HTML is the standardized markup language for creating documents on the web. 

This includes titles, headings, texts, and links. It is the most common and primary language used in web page development.

CSS is a language, along with HTML, that allows a programmer to set the style of a web page. Here we refer to the design, colours and fonts, and these elements are separate from the main code of the website.

JavaScript is the solution for animations, games, applications and interactions on a web page. All the dynamic effects of a page are created with this programming language. 

There are more languages, such as PHP, Perl, ASP, Net, Python, and Ruby; Choose the most interesting and useful one for you and use it.

Mastery of HTML5 and CSS3 languages

HTML  and  CSS languages will be essential since you will develop all the visible parts. You will use the HTML to build the site’s structure, while the CSS will intervene when dressing the web page. It is essential to have a good knowledge of the latest versions.

Rest APIs

Businesses often use REST APIs to manage data between the web and back-end software.

An API, or application programming interface, acts as an intermediary between 2 other programs to exchange information. For example, sending a message online uses an API.

REST stands for Representational State Transfer. It is a computer system in which developers can create APIs. REST is a popular framework in data management, so it is clear to Ravisankar that it is a popular skill among businesses.


Testing is a big part of the web page development process, not just code and design. A web developer is a parser to a certain extent. Before presenting the final product (for example, a web page) to your client, make sure that everything is done correctly:

Know the Versioning

Version control is a fundamental developing concept. Thanks to software support, it is possible to manage the different versions. 

Without losing previous versions, you will work directly on the project’s source code with these specific tools. So your recruiter will expect you to have a good command of version control, mainly through  Git software,  which is the most popular on the market.

Gain Experience

The next step is to gain experience in your field of study. In this way, you will become familiar with the sector, improve your programming skills and increase your employment possibilities.

The easiest way to get started is to accept volunteer jobs. For example, you can create a simple business website for a local store or build an event website to promote them. 

You may work for free, but your experience will be a valuable element in your job search. In addition, you can contribute to your community.

As in all professions, technical problems are not necessarily the most fun part of the job, but you should stick with them. As a Front-End developer, you will be in charge of managing all the errors that may occur in the interface.
