Frontend, Backend and Fullstack Developers


In the world of web and application development, there are three fundamental roles: frontend developers, backend developers and fullstack developers. Each of these roles plays a critical role in web and application development, and the choice between them depends on each developer's skills, interests and career goals. In development teams, it is common to combine these roles to make the most of the strengths of each one and achieve successful projects, in this article we will show you in detail their functions, as well as the advantages and disadvantages that differentiate them.

Frontend Developer

A frontend developer is a programming professional who specializes in creating the user interface of an application or website. Their main focus is on the visible part of the application, what users see and interact with directly on their browsers or devices. Frontend developers use technologies such as HTML (HyperText Markup Language), CSS (Cascading Style Sheets) and JavaScript to design and develop the appearance and functionality of web pages. They are responsible for ensuring an attractive and optimized user experience, as well as page loading speed.


  • Attractive User Interface: Frontend developers focus on the visible part of an application or website. They are responsible for creating an attractive and friendly user interface for the end user.

  • User Experience: They work on improving the user experience, optimizing loading speed and navigation.

  • Creative Skills: Frontend developers often have design skills and knowledge of technologies such as HTML, CSS and JavaScript, allowing them to bring creative designs to life.


  • Limited to Frontend: Their focus is limited to the user interface, so they are not involved in implementing business logic or database management.

  • Backend Dependency: Their work often depends on backend developers for data and functionality.

Backend Developer

A backend developer is a programming professional who focuses on the non-visible part of an application or website. Their work focuses on business logic, database management and security. Backend developers create and maintain the servers, databases and systems that allow an application to function properly. They use a variety of programming languages, such as Python, Java, Ruby, PHP or Node.js, to develop the logic that drives applications and to ensure that data is stored and managed efficiently and securely.


  • Data Management: Backend developers focus on business logic and data management. They are responsible for ensuring that the application works correctly from a data management and security point of view.

  • Scalability: They have the ability to design scalable systems that can handle large amounts of traffic and data.

  • Security: They can implement robust security measures to protect sensitive information.


  • Less Visible: Their work is less visible to the end user, as it is in the "hidden" part of the application.

  • Requires Advanced Technical Knowledge: Often, backend development involves a broader set of technical skills and a deep understanding of multiple programming languages and databases.

Fullstack Developer

A fullstack developer is a professional who has skills in both frontend and backend development of applications and websites. They are versatile and can work on all parts of a development project. Fullstack developers can design the user interface, implement business logic and work with databases. They have the ability to understand and manage the entire workflow of an application, which allows them to be more autonomous on smaller projects or startups. However, they often have less in-depth specialization compared to developers specializing in frontend or backend.


  • versatility: fullstack developers have both frontend and backend skills, allowing them to work on all parts of an application.

  • Autonomy: They can develop smaller projects independently and fully understand the workflow of an application.

  • Adaptability: They are able to switch from one area to another according to the needs of the project.


  • Limited Specialization: Often, fullstack developers do not have the same deep specialization in frontend or backend as developers dedicated to a single area.

  • Increased Workload: On complex projects, they may feel a heavier workload from having to address all aspects of development.
