Frontend, backend or fullstack — which path?

Almost every developer career starts with the same question: do you build the side users see (frontend), the logic and data behind it (backend), or both (fullstack)? No choice is final, but it shapes your first years and your tech stack.

Frontend

Frontend developers build the interface: everything that runs in the browser. You work with HTML, CSS and JavaScript/TypeScript, plus a framework like React, Vue, Angular or Svelte. The focus is on performance, accessibility and UX. Visual and detail-oriented? Frontend will feel like home.

Backend

Backend developers build the APIs, services and data layer: the logic users don't see. Languages like Node.js, Python, Java, Go, C# or PHP, with databases (PostgreSQL, MongoDB, Redis) and increasingly cloud and microservices. Love data models, scalability and systems that hold together? Backend fits.

Fullstack

Fullstack developers work across the whole stack — from database to UI. Popular at start-ups and scale-ups where one engineer ships a feature end to end. You don't need to be an expert in everything; the strength is breadth and switching between layers.

Which path fits you?

Look at what energises you and at the jobs: filter by the frontend, backend and fullstack categories and see which stacks and companies appeal. The Developer Salary Report shows median ranges per direction in the Netherlands and Flanders.
