About Roger

Hello, my name is Roger.


Freelance developer for over 10 years (42 School graduate), I help project owners transform an idea into a reliable, high-performing, and truly used digital product:mobile application, website or web application, and artificial intelligence integration.

Many arrive with a clear idea in mind, but the technical side seems opaque to them - and they look for someone who explains simply, without jargon, and who takes the time to understand their business before coding. This is exactly how I work.

Mobile Application (iOS & Android)

React Native development, clean and scalable architecture, API integration, authentication, payments, notifications, App Store & Play Store publishing.

Web Application & Website

Web applications, back-offices, landing pages, and custom websites (PHP / Laravel, PWA), designed to be clear, fast, and accessible (RGAA, GDPR).

Artificial Intelligence & Automation

Integrating AI into your products - chatbots, intelligent assistants, content generation - and automating processes to reduce costs and save time.

End-to-End Support

From idea to design, from development to launch, with business advice and monetization strategy. A single point of contact, direct and transparent communication, and a pace adapted to yours.

---

They trusted me:M6, INRAE, Mots Croisés Magazine, as well as numerous startups and freelancers - with the same goal: to deliver a clear, robust, and useful application.

Whether you have an app idea, a prototype to turn into a real product, or an existing project to improve, I'd be delighted to discuss it with you.
