React Developer Vs. Similar Roles
| Role | Main focus | Primary metric |
|---|---|---|
| React Developer | Building user interfaces with React | Page performance, UI defects |
| Frontend Developer | Building web interfaces with any framework | Page speed, accessibility |
| Full-Stack Developer | Building both front-end and back-end features | Features shipped end to end |
| Backend Developer | Building servers, APIs, and databases | API reliability, latency |
At smaller companies, one React developer often builds the interface and a few back-end endpoints too. Add a dedicated back-end or full-stack hire once the API and data layer need their own owner.
