Hard skills and soft skills

Full stack developer list of skills required

In order to be a successful full-stack developer, there are certain skills you’ll need to master. Hard skills include extensive knowledge of programming and development, sound mathematical knowledge and logical thinking, as well as the ability to analyze codes and recognize problems in them.

  • HTML
  • CSS
  • JavaScript
  • Ruby
  • PHP
  • Python

Soft skills, on the other hand, include the ability to work within a team, to work independently and to be highly motivated.

Background and Requirements

The prerequisite to becoming a full-stack developer is usually an academic education at a university or college. Since programming is still a rather young science and the working world is strongly results-oriented, IT specialists can find their way into the job.

With the pursuit of further education being especially relevant in the industries where programming languages are used, programmers who continue their education at a Master’s level are always at an advantage.


Specialization is particularly useful in the area of programming languages. Since 100% proficiency is more valuable in practice than the number of superficial skills, a full stack developer often focuses on the most common languages such as HTML, CSS, Java and other topics that serve niches or are competitive in the job market.

Typical industries

Since Full Stack Developers are hardly limited in their programming skills, they are represented in almost all industries. They can plan, develop and revise projects, such as programs from Adobe, but are also needed in industries such as gaming, IT, medical, security, etc. 

Apart from large scale operations, a full stack developer is also invaluable for certain small businesses. With their ability to take on a large variety of responsibilities, hiring a full stack developer is great for businesses that may not be able to hire multiple employees.
