Full Stack Engineer — FAQ
- What is a Full Stack Engineer?
- A Full Stack Engineer builds and maintains both the frontend (what users see) and the backend (APIs, databases, business logic) of a web application — owning the full product layer from browser to database. Common stacks include React + Node/Python/Go, and Next.js + serverless.
- Full Stack vs. Backend vs. Frontend Engineer?
- Backend engineers focus on APIs, databases, and server-side logic. Frontend engineers specialise in UI, performance, and the browser. Full Stack engineers do both — often at startups or product teams where end-to-end ownership is more efficient than specialisation.
- What skills do Full Stack Engineers need?
- Frontend: HTML/CSS, JavaScript/TypeScript, React or Vue. Backend: Python, Node.js, Go, or similar; REST/GraphQL APIs; SQL and NoSQL databases. DevOps basics: CI/CD, Docker, cloud deployment. AI-era full stack roles add LLM API integration and streaming UX patterns.
