What is Full-Stack Developer?
Quick answer
A developer who works on both the frontend and backend of an application, from user interfaces to servers and databases.
Full-Stack Developer, explained
A full-stack developer is comfortable across the layers of a typical web application: building interfaces in the browser, writing server-side logic, designing databases, and often handling deployment. A common combination is JavaScript or TypeScript with React on the frontend, Node.js or Python on the backend, and a SQL database.
The role is popular at startups, where small teams need people who can ship complete features end to end. Being full-stack does not usually mean being an expert at everything; most full-stack developers have deeper strengths in one area. Aspiring developers often build a portfolio of complete projects, such as a blog or task app with user accounts, to demonstrate these skills to employers.
