Freelance React developer
React developer for modern, high-performance interfaces
When your interface calls for interactivity, real-time updates or a true app-like feel, React comes into play. I pair it with TypeScript and Tailwind to deliver clean UIs that you can evolve over time without breaking everything.
React is my front-end tool of choice when the interface calls for interactivity, real time or an 'app' feel. I use React with TypeScript, Tailwind and proven libraries to deliver maintainable, typed and testable UIs.
React is a library for building interfaces. Its core idea is simple: you break your screen down into components — a button, a product card, a table, a form — and each one handles its own rendering. When the data changes, React takes care of updating only what changed, without reloading the whole page. This is the mechanism that makes rich interfaces pleasant to build and smooth to use, and that lets you reuse the same building blocks from one screen to the next without duplicating code.
Where React really makes the difference is in everything that responds live: a filter that narrows a list as you type, a cart that updates instantly, a dashboard whose figures change in real time, drag and drop, a complex form with immediate validation. On a classic editorial website, this level of interactivity is pointless and would only weigh the project down. On a business application or a SaaS, it is exactly what separates a tool you put up with from a tool you genuinely enjoy using every day.
I never use React on its own. I systematically pair it with TypeScript to catch errors before they reach production, with Tailwind for styling that stays consistent and quick to maintain, and with proven libraries rather than reinventing things in custom code. In practice, that means React Query for server data, Zustand for UI state, React Hook Form and Zod for typed forms, Radix or shadcn for components that are accessible from the start. The goal is not to pile up trendy tools, but to reach a solid, readable foundation — readable by the next developer who works on it, or by me, six months later.
Accessibility is not an option I bolt on at the end. A poorly designed React interface can quickly become unusable with a keyboard or a screen reader, because native browser elements get replaced by custom components. So I rely on accessible primitives, I manage focus, ARIA roles and keyboard navigation, and I aim for WCAG AA criteria. A beautiful interface that shuts out some of your users is not a successful interface.
This is the question that comes up most often, and it deserves an honest answer rather than a sales pitch. A "classic" React application — a SPA that loads everything in the browser — is poorly equipped for SEO: on the first load, Google receives a nearly empty page, and the content only appears once the JavaScript has run. For an internal tool, a back office or a client area, this doesn't matter at all — nobody searches Google for your dashboard. For a page that needs to be found, it is a real handicap that has to be addressed from the start.
The solution is not to abandon React, but to render it on the server. With Next.js or hybrid rendering, the server sends a page that is already filled in and perfectly readable by search engines, then React takes over for the interactivity. You keep the comfort of React without sacrificing visibility. This is exactly what Inertia enables, the stack this portfolio is built on: modern React running on a Laravel back end that serves real HTML, with server-side rendering switched on wherever SEO matters.
The right instinct, then, is not "React or no React", but "which rendering for which goal". A showcase site that lives off local SEO often doesn't need React at all — a well-optimized WordPress or a Laravel site is more than enough and costs less to build and to maintain. An application that needs to be both findable and to offer a rich experience will go for server-rendered React. I frame this choice with you right from the start, because it shapes the rest of the project: the architecture, the budget and even the hosting.
Beyond rendering, the SEO of a React application also comes down to perceived performance. Google looks at Core Web Vitals — loading speed, visual stability, responsiveness to clicks — and a neglected React interface can degrade them. So I keep an eye on the amount of JavaScript shipped, I split the code to load only what is needed, and I test under realistic network conditions, not just on an office fibre connection. A fast page is better for SEO and for your users alike: both goals pull in the same direction.
A React interface is only worthwhile when it is connected to real data. This is where my full-stack profile changes things: I don't deliver a disconnected front end that someone else has to wire up afterwards. I also build the API that feeds it, in Laravel or Symfony, and I handle the points that usually eat up time — authentication (Sanctum or JWT), CORS configuration, pagination, server-side filtering, fine-grained error handling on the interface side. The front end and the back end are designed together, not glued back on at the end.
When the front end and the back end speak the same language, a lot of integration bugs disappear before they even exist. I share types across both sides, via OpenAPI or generated types, so that a field renamed in the API flags itself immediately in the editor, rather than three weeks later in front of a user. For server data, I rely on React Query — caching, automatic refetching, handling of loading and error states — and I deliberately keep UI state lightweight with Zustand. Less state to synchronise by hand means fewer surprises in production.
On the flows that matter, I write tests: Vitest for logic and components, Playwright for end-to-end scenarios such as logging in or placing an order. The goal is not coverage for the sake of coverage, but confidence: being able to change the interface six months later without fearing you'll break what already worked. This safety net is what lets an application evolve without the fear of change piling up.
This way of working applies just as well to a brand-new project as to a React layer added on top of an existing system. Do you already have an API, or an ageing back office to modernise without rewriting everything? We can introduce React gradually, screen by screen, starting with the areas where interactivity brings the most value, rather than rebuilding everything in one go. It's less risky, faster to get into production, and it keeps your business running during the transition instead of putting it on hold for months.
I'm a freelance developer based in Martinique, and I work just as well with organisations in the French Caribbean as with clients in mainland France or further afield. On a React project, distance is a non-issue: everything goes through versioned code, regular check-ins and deployed previews that you can test in real conditions at every step. You watch the interface take shape, you react early, and we adjust before going back is costly. Transparency replaces grand announcements.
For a Martinican company, the value of having a contact on the ground and in your time zone is concrete: we can meet, talk without any lag, and I understand the local context. Usage is overwhelmingly mobile, connections aren't always those of mainland France, and a small Caribbean business doesn't have the same needs as a large Paris-based group. A React interface, here, is above all an interface that has to stay fast and readable on a phone, on a network that can be temperamental — and I design with that in mind, rather than learning it after going live.
Before writing a single line, I take the time to scope things out: what the tool has to do, for whom, which screens are truly the priority. Many projects get bloated because everyone wanted everything, all at once. I prefer to deliver a solid, useful first version, put it in your hands, then build on it from real usage. This avoids paying for features no one will use and gets your tool into service faster.
Finally, I don't disappear once the project is delivered. The code is documented, typed and tested so you're never tied to a single person: another developer can pick up the work without having to rediscover everything. I offer follow-up for further development and maintenance, and 30 days of support are included after launch. React moves fast; my role is to deliver a healthy foundation today and to support you so it stays that way tomorrow, without technical debt quietly building up.
The advantages
- Rich, responsive interfaces: dynamic filters, real time, drag and drop, complex forms — with no page reloads.
- TypeScript across the board: integration errors flag themselves in the editor, not in production.
- A mature, stable ecosystem: React Query, Zustand, Radix, shadcn — proven building blocks rather than fragile custom code.
- Front and back from the same person: Laravel or Symfony API, authentication, CORS and shared types handled end to end.
- Accessibility taken seriously: accessible components, keyboard navigation and WCAG AA criteria from the design stage.
- Gradual integration possible: an existing system can be modernised screen by screen, without rewriting everything.
Limitations to be aware of
- Not suited to a simple showcase site: for editorial content that lives off SEO, a WordPress or a Laravel costs less and does the job better.
- SEO for a pure SPA is weak: without server-side rendering (Next.js, Inertia), a React page arrives empty for Google.
- More JavaScript to load: on a slow network or an entry-level phone, a React interface needs care to stay fast.
- A real setup cost: design system, typing and tooling represent an upfront investment that is only justified when interactivity requires it.
React is excellent for rich interfaces, but it's rarely the right tool for a classic website. Here's how I decide based on your project, without selling you complexity you don't need.
Choose React if…
- You're building a SaaS, a dashboard or a business tool with plenty of interactions.
- Your interface needs real time, instant filters, drag and drop or complex forms.
- You want a typed and tested application, designed to last and evolve over time.
- You already have an API (Laravel, Symfony, headless) to dress up with a modern, fluid front end.
- You're planning a technical team: React is easy to hire for and its ecosystem is well charted.
Prefer something else if…
- Your project is a showcase site or a blog that has to rank well first: WordPress or Laravel are enough.
- The content is mostly editorial and managed by you: a CMS stays more direct day to day.
- The budget is tight and the interactivity stays basic: no need to pay the extra cost of a React stack.
- You sell online on a standard model: WooCommerce gets you up and running far faster.
- Local SEO is your absolute priority and the interface is secondary.
- SaaS application interfaces
- Advanced dashboards and back-offices
- SPAs or hybrid applications with APIs
- Reusable front-end components and design systems
