React Developer, Full Stack Developer, Web Developer: Who Does What?

Web developer, front-end developer, React developer, back-end developer, full stack developer. The titles overlap and blur, and when you are hiring, it is genuinely hard to know which one you need. Here is what each actually means, without the jargon, so you can hire for what your project requires rather than for a buzzword.

Front-end: what you see

A front-end developer builds the part of the website you see and touch: the layout, the design, the buttons, the way things respond when you click. A React developer is a front-end developer who specialises in React, which is the most widely-used tool for building modern website interfaces. When someone says React developer, they usually mean a skilled front-end developer using the current standard tools.

If your project is a marketing website or the visible part of an app, front-end skill is what makes it look and feel good.

Back-end: what you do not see

A back-end developer builds the engine behind the website that you never see directly: the database that stores your data, the logic that processes a payment, the system that sends an email when someone fills a form, the security that protects user accounts. When a website does something, remembers something, or connects to something, the back-end is doing the work.

A brochure website barely needs a back-end. An application with logins, payments, bookings or dashboards is mostly back-end work under the surface.

Full stack: both ends

A full stack developer works across both the front-end and the back-end. They can build the interface you see and the engine behind it, and connect the two. For most business projects, this is the most useful kind of developer, because a website or app is rarely just one or the other. Someone who understands the whole stack makes decisions that fit together, rather than handing off between specialists who each optimise their own half.

Which one you need

For a marketing website, you mainly need strong front-end and design ability, plus enough back-end for forms and integrations. For an application, a portal, a store, or anything with accounts and data, you need genuine full stack ability, or a team that covers both ends.

The trap is hiring a pure front-end person for a project that is secretly full of back-end work, or the reverse. This is why a clear written scope matters: it reveals what the project actually requires before you hire. I work as a full stack developer precisely because most business projects need both ends handled by one accountable person, rather than split across a handoff where things fall through the gap.
