Full-stack developer

A full -stack developer can build both the browser part (front end) and the server part (back end), and connect a database. This developer has an understanding of all the technologies essential for a project. This requires a lot of time and experience, which is why why full-stack engineers are relatively difficult to find.

Such developers are indispensable in startups, for example, to quickly create and maintain an MVP. Their remuneration is usually quite high ; however, the presence of a competent full-stack programmer reduces the cost of the project as a whole. They can quickly develop a prototype, solve a variety of issues and complexities, and do not spend much time communicating within the team as they work independently.

The main value a full -stack developer brings is that they can see the big picture, plan the application structure, and participate in all stages of development — from server logic to client code.

Job responsibilities

The responsibilities of a full -stack developer largely depend on both their experience and the project they are working on. The main responsibilities usually look like this:

  • Develop the structure and architecture of a website or application
  • Build adaptive, cross-platform applications, write code for the server and client parts of the project
  • Integrate external services on the front and back end
  • Design and develop APIs
  • Debug.


In startups, their responsibilities can be described briefly as "Do everything regarding the development". This includes the tasks of both frontend and backend developers.

In large companies, full-stack developers can be team leaders who are responsible for designing applications and assigning tasks.



The list of skills a full -stack developer needs is extensive. It includes:

  • Browser side: JavaScript (ECMAScript 6) programming language, jQuery library, Angular, Vue, or React framework
  • Server side: at least one "server" programming language, such as PHP, Ruby, Java, or Python, platforms ASP.NET and Node.js, and frameworks such as Rails (for Ruby), Django (Python), Laravel (PHP) 
  • Databases: SQL, MongoDB, and others
  • Version control systems (popular ones are Git, SCCS, RCS, Mercurial, Bitbucket)
  • Best practices of security.


There are certain well established combinations of programming languages, frameworks, and tools (called “ stacks” of technologies). For example, Microsoft Full Stack Certification includes C#, SQL, HTML, CSS, JS, Patterns, and AngularJS (optional).


Other examples of technology stacks used:

  • LEMP: JavaScript - Linux - Nginx - MySQL - PHP
  • Django: JavaScript - Python - Django - MySQL
  • Ruby on Rails: JavaScript - Ruby - SQLite - Rails
  • MEAN: JavaScript - MongoDB - Express - AngularJS - Node.js


It would be a plus if a full -stack developer has time to follow all the important trends. However, with such a wide range of professional interests, that 's not easy.

We have collected answers to the most common questions from companies in search for full-stack developers. If you still have any questions, our experienced INDIGO tech recruiters will be happy to answer them.

1. How do I find a competent full -stack developer?

Good full-stack developers usually have a heavy workload and are always busy. You can find them through LinkedIn or other social networks, not on job boards. Due to the fact that such specialists are in high demand, they do not usually have to actively look for work. The main question is how to convince a suitable candidate to communicate with a recruiter at all and, even more so, to change the company they are working for . One option is to offer an interesting project and the ability to delegate routine tasks (that is, not to do everything themselves , but to hand some work off to a frontend or backend developer ).
Although a full -stack developer can develop the architecture, write the client-side and server-side code of an application, they ' re not almighty. You will need at least a designer and a QA specialist. In principle, a full-stack developer can handle testing, but it's hardly practical wasting their time on it. To create an MVP, in most cases, the above-mentioned team of three specialists will be enough , but a team of a full -stack developer and specialists in specific programming areas is more effective, especially on large projects.
As a rule, the knowledge and experience of a full-stack developer in each individual area is not as deep as that of narrow specialists. However, it's usually enough for the main task — forming a vision of the overall picture and designing the application. Also, the model of a T-shaped developer ( in other words, a professional with T-shaped expertise) , is becoming more and more relevant. This is a specialist who has deep knowledge in one area and some understanding of many others.
A full -stack developer knows at least JavaScript and one "server" programming language (or Node.js platform), and can work with databases.
