Hi, I'm Hadrien

After 20+ years of building software professionally, I'm shifting gears into indie-hacking. I want to create products that I love using — and hopefully, ones that others will find valuable too.

In the meantime, I'll keep an eye open for contracting work. If you need a hand kickstarting a project or leveling up an existing codebase I'll be happy to help, just reach out.
