Freelance PHP developer for custom web applications

PHP powers a huge part of the web, and it's the language I'm most comfortable with. Tell me about your project: I'll give you an honest answer on whether PHP is the right fit, and how to do it well.

PHP runs a large part of the web — and it's the language I'm most comfortable with, from WordPress to modern frameworks like Laravel and Symfony. Typed, tested and maintainable code: I write clean PHP, not 2010-era PHP.

PHP carries a reputation as a hacked-together language, inherited from the 2000s when HTML, SQL and logic all got mixed into a single file. Those days are over. The PHP I write today is typed, structured and tested: typed properties, enums, attributes, return types, match expressions. In practical terms, your application becomes easier to read, errors surface earlier, and the code can be picked up again years later without having to guess how it works.

On the performance side, PHP 8 has come a long way. The engine is significantly faster than PHP 7, OPcache keeps the compiled code in memory, and for the heaviest workloads the JIT kicks in. For the vast majority of brochure sites, online stores and business applications, PHP handles the traffic effortlessly, on affordable hosting. We're a long way from the image of a slow, fragile language.

Above all, PHP isn't an isolated language: it's the foundation of WordPress, Laravel and Symfony. Mastering PHP in depth means being able to step in anywhere across that ecosystem, whether it's a WordPress theme, a business module in Symfony or a full Laravel application. It's also what lets me recommend the right tool rather than sell you the one I happen to know.

This versatility has a very concrete impact on your budget: you're not locked into a single technology or dependent on one provider. Clean PHP code can be handed over to another developer without an initiation ritual, the hosts that support it number in the thousands, and the documentation and community are among the richest on the web. For a small business or a sole trader, that's the guarantee of not being stuck two years from now with an application no one can pick up anymore.

My approach to PHP comes down to three words: standards, tests, security. I rely on the PSR conventions so the code stays readable for any developer, on Composer to manage dependencies cleanly rather than copy-pasting libraries, and on a reproducible environment so that what works on my machine also works in production. Nothing exotic: these are the foundations every serious PHP project should have.

I don't test everything for the sake of testing, but I systematically cover the sensitive paths with PHPUnit or Pest: payment, authentication, business logic, form validation. These are the places where a bug is costly and goes unnoticed. With those tests in place, I can evolve your application without fear of breaking what already worked, and you gain peace of mind over the long run.

Security is part of development, not an optional service billed separately. Prepared statements against SQL injection, validating and escaping input, CSRF protection on forms, sound session handling, security headers on the server side: these are reflexes built in from the very first line, not a layer bolted on at the end. A poorly protected site always ends up paying for it, both in exposed data and in reputation.

Plain PHP or a framework? It depends on the project, and I'll settle it with you without dogma. For a focused script, a small integration or a utility, lightweight, well-organised PHP is more than enough. As soon as there's business logic, users to authenticate, data to model seriously, Laravel or Symfony bring foundations that save time and avoid reinventing authentication, routing or the database layer. The goal stays the same: the simplest solution that genuinely meets your need.

A large share of the requests I receive aren't about a brand-new project, but about code already in place: a site still running on an old version of PHP, a homegrown application with no tests that nobody quite understands anymore, or a WordPress theme weighed down by years of patches. Taking over this kind of codebase calls for method, not a sledgehammer that breaks everything along the way.

I always start with an audit before touching the code: the PHP version and the implications of upgrading, the state of the dependencies, security weak points, the presence or absence of tests, the riskiest areas. You get a clear picture of what you own and a prioritised action plan, from the most urgent to the most comfortable. We know what we're doing, in what order, and why — without discovering problems at the last minute.

Then I stabilise and modernise gradually, without rewriting everything in one go. We secure things first, add tests on the critical parts, raise the PHP version in controlled steps, and isolate the risky code. This approach limits nasty surprises and spreads the effort over time, which is often more realistic for the budget of a small business or a sole trader than a complete overhaul. At every step, your application stays online and usable: we move forward in small, verified increments, not in one leap into the void.

Let's be clear-eyed: not all legacy code deserves to be saved. When a codebase is too fragile, poorly designed from the start or built on dead dependencies, I'll tell you so honestly, and we'll make a fair comparison between the cost of bringing it up to standard and that of a targeted rebuild. The goal is never to bill as many days as possible, but to leave you with an application you can rely on, and one you can evolve without fearing a domino effect.

Beyond brochure sites, this foundation lets me build a wide range of things: a back office to run your business, a client area where your users find their documents and orders, an API that lets your site talk to invoicing software or a CRM, or automations that save you hours of manual data entry. PHP is perfectly comfortable with real business logic, as long as it's written with method.

I'm based in Martinique and I work with clients across the Caribbean islands, in mainland France and beyond. Distance is no obstacle for PHP development: everything goes through versioned code, clear written exchanges and regular check-ins. For a shop owner in Fort-de-France just as for a Paris-based organisation, the collaboration runs the same way, and you always know where your project stands.

The advantage of a single freelance developer is the direct point of contact. You're not dealing with an anonymous team or a project manager who filters everything, but with the person who actually writes the code. I explain my technical choices in plain language, without needless jargon, and I'll tell you honestly when an idea will cost you a lot for little benefit. It's more efficient, and it avoids misunderstandings.

When it comes to SEO and performance, PHP plays a real role on the server side: controlled response times, caching, HTML rendered cleanly for search engines. A well-built PHP site lays solid foundations for your local SEO in Martinique and elsewhere, without relying solely on cosmetic tweaks added after the fact. Speed and clean code matter as much as keywords, and a Google that finds you quickly means a visitor who stays.

Finally, hosting remains one of PHP's great everyday strengths. Simple shared hosting is enough to get most projects off the ground, and you can move up to a dedicated or managed server as the business grows, without rebuilding everything. I advise you on the option suited to your budget and your real traffic, set up the server properly, and stay reachable afterwards for updates and maintenance — not just for the duration of the delivery.

The advantages

  • The most widespread language on the web: it powers WordPress, Laravel and Symfony, with hosting available everywhere and at an affordable price.
  • Modern PHP 8, typed and fast (OPcache, JIT): far from the clichés, it comfortably handles the load of sites and business applications.
  • Clean, standardised code (PSR, Composer) that can be picked up and evolved painlessly, rather than a patchwork of quick fixes.
  • Security built in by default: prepared statements, validation, CSRF protection, sound sessions, security headers.
  • Automated tests (PHPUnit, Pest) on the sensitive paths so the application can evolve with confidence.
  • One foundation for custom work, WordPress or a framework: I choose the tool suited to your need, without dogma.

Limitations to be aware of

  • For intensive real-time work (chat, live notifications, large numbers of simultaneous connections), Node.js is often more comfortable than PHP.
  • PHP is a server-side language: for a highly interactive, app-like interface, it needs to be paired with a modern front end (React, Inertia).
  • Quality depends entirely on discipline: without typing, tests or standards, a PHP project can quickly become hard to maintain.
  • Legacy code left without updates ages badly and accumulates security risks: maintenance isn't optional.

PHP isn't the answer to everything, and I'd rather tell you that up front. Here's when it stands out as the pragmatic choice, and when another language or technology will be a better fit for what you want to build.

Choose PHP if…

  • You want a site or business application (brochure site, store, back office, client area) with simple, economical hosting.
  • Your project is based on WordPress, Laravel or Symfony, all of which run on PHP.
  • You have an existing PHP codebase to take over, stabilise or gradually modernise.
  • You're looking for a proven, well-documented foundation that's easy to host and to maintain over time.
  • You want a good balance between development cost, performance and ease of maintenance.

Prefer something else if…

  • Your product relies on intensive real-time work or many simultaneous connections: Node.js will often be a better fit on the server side.
  • You're primarily building a native mobile application: we'd lean towards a dedicated mobile stack.
  • The interface is the heart of the project and demands very advanced interactivity: it calls for a React front end, possibly via Inertia.
  • You already have a team fully trained on another server-side language that would be costly to switch.
  • Your need comes down to scientific computing or data work: other ecosystems are better equipped for that.

  • Custom business applications and back-offices
  • APIs and integrations between tools
  • Taking over and modernising legacy PHP code
  • WordPress / Symfony / Laravel modules and extensions
