About
Websites, tools and mods, built end to end.
End to end
From the data pipeline and the API to the screen in front of the user.
Numbers that hold
Messy data in, numbers you can trust out.
Written down
Every decision documented, so the next person can pick up where I left off.
I've spent 8+ years building software end to end - enterprise features for a B2B SaaS used by Carrefour, Leclerc and Nestlé, then a data-exploration tool I designed and shipped solo for hospitals and emergency services. These days I run my own products: a full-stack analytics platform, a Warframe build tool, and Rust desktop apps, with an AI-native workflow built on Claude Code. I like problems where the data is messy and the numbers have to be right, and I write down every decision so the next person can follow it.
