I build your web and mobile app, from the idea to production, then help it grow.

Freelance developer, I design, build and launch web and mobile applications, then look after them and improve them, release after release. Backups, security and app store publishing are part of the job. And I bring artificial intelligence in when it helps, with its cost and reliability measured.

Release allowed

Every version of this site's assistant reruns these 36 cases before it goes live. Below the threshold, it doesn't ship.

They say it better than I do: founders who trusted me with their product.

Florian joined my startup as CTO. It changed the whole dynamic! Beyond his technical skills, what I appreciated most was his mindset: with Flo, anything is possible as long as the request makes sense.

When he arrived, he told me: “I'm going to move you from a bicycle to a Lambo.” He did. In three months we changed dimension — a product rebuilt around the real need and the end customer. I recommend him without reservation.

CEO, Pango Sports

I had the chance to work with Florian on building my CRM platform, and I can only recommend him warmly.

From our very first conversations, Florian understood the specific needs of my business and turned them into clear, effective technical solutions. It's rare to meet a developer who combines that level of technical rigor with genuine listening skills.

Throughout the project he was responsive, reliable and full of ideas. Communication was always smooth, and he delivered a CRM platform that is functional, intuitive and perfectly tailored.
