An independent web developer, not an agency
Based in Valenciennes, I support companies, freelancers and project owners across the Valenciennes area and the Hauts-de-France in building their web tools. You deal directly with the person who writes the code, makes the technical decisions and stays available after delivery — no subcontracting, no middleman.
Whether you need a fast, well-ranked showcase site, an online store, a client portal, a web-based business application or an API that connects your software, I design a solution built around your real-world processes — robust, secure and scalable.
20 years of hands-on work on real projects, from .NET back-ends to modern interfaces: well-considered technical choices rather than passing trends.
What I build
- Custom showcase and corporate websites
- Web platforms and client portals / extranets
- Business web applications (management, tracking, automation)
- Online stores and e-commerce building blocks
- REST APIs and back-ends (ASP.NET Core, PHP, Node.js)
- Modern front-ends (React, Vue.js, TypeScript)
- Taking over, redesigning and optimising existing sites
The right tools for a fast, durable web
Back-end
ASP.NET Core, PHP, Node.js, SQL Server — solid servers and APIs, built to last and to scale.
Front-end
React, Vue.js, TypeScript, polished HTML/CSS — accessible, responsive and high-performance interfaces.
Performance & SEO
Core Web Vitals, loading times, structured data — a site ready to be found on Google.
A local web developer in the Valenciennes area
Working with a web developer from the region means being able to meet up to scope the project, sign off on a mock-up or train your teams. I work in Valenciennes and across the whole metropolitan area — Anzin, Denain, Saint-Amand-les-Eaux, Condé-sur-l'Escaut, Marly — as well as in Maubeuge, Cambrai, Douai, Lens and Lille. Most engagements can also be handled entirely remotely, throughout France.
