What Does a Full-Stack Developer Do?
A full-stack developer builds both the frontend (what users see) and the backend (server, database, APIs) — the entire vertical slice of a software product.
Frontend:
- React, Next.js — building what users interact with
- Responsive design, accessibility, performance optimization
Backend:
- APIs, database design, authentication and authorization
- Serverless functions and edge deployments
Infrastructure:
- Deployment pipelines (Vercel, Netlify)
- Environment management, error tracking
Mobile (sometimes): Not every full-stack developer covers mobile. I do — Flutter — which means I can build a web app and its companion mobile app without switching teams.
Full-stack vs. specialist: Full-stack wins for MVPs. Specialists win for teams of 20+ working on a mature product.
