01 / About

A working CTO, available for your project.

I don't run a faceless agency. You talk directly to the person writing the code — someone who ships a product to real users every single day.

What I do

Native iOS apps, web platforms, and AI-integrated products. My day job as CTO means everything I build is shaped by what it takes to run software in production — not slideware.

How I work

Small and direct. No account managers, no hand-offs. Prototypes in days, production code with the rigor a working CTO insists on.

Right now

CTO at BeatPitch, building Typpo — turning your voice into video. Plus Clean Challenge and a daily experiment called Claude of the Day.

Off the clock

A career spent across France, the UK and Switzerland. When the laptop closes: family in Etagnières, photography, lake swims, weekends in the van.
