About
Marc Muller
40. Based in Metz. Entrepreneur since forever, developer by necessity.
I grew up around bakeries — surrounded by entrepreneurs who get up early and build things with their hands.
That stuck. Since then, I've spent ten years in construction and real estate, then ten years in escape rooms — first physical, then online. Every time, the same instinct: build my own tools. Physical mechanisms, code, entire systems rigged together so things run exactly how I want them.
I'm not a trained developer, but I've always had my hands in tech — pushed along by people close to me who've been swimming in it for years.
I built websites for every business I ran. Or rather: I struggled to. For years, it was the frustrating part — having a clear vision but not the right tools to get a clean result out.
Today, the tools have caught up with people like me. I build fast, well-ranked websites to 2026 standards — for my own projects and for other people's.
I work mainly in the Grand Est region (Strasbourg, Metz, Nancy, Colmar, Mulhouse) but I'm fully remote-friendly — clients anywhere in France or Europe.

What I love about this job
Meeting people. Every client is a different trade, a different story, a different problem to solve. After twenty years building businesses in very different worlds, that's what keeps me going: understanding what you do and making it visible.
And learning. All the time. New tools, new techniques, new ways to do things. The web moves fast — people who stop moving fall behind. I'd rather stay curious. That's how I make better sites every month.
My approach
Custom, not copy-paste
Every site is built from scratch. Your business is unique — your website should be too.
Speed is not optional
A slow site loses visitors. Every project targets 100/100 on Lighthouse. Good for users, great for SEO.
SEO from day one
Visibility is built into the structure. Technical SEO, Schema.org and GEO (AI search) are included in every project.
Honest timelines
I deliver in 7 days on average. I don't over-promise, and I keep you in the loop at every step.
When I'm not in front of a screen, I'm probably underwater. Certified Divemaster — I sometimes work from Thailand between dives. Remote, not disconnected.
