Software Engineer & Indie Hacker. Ten years of web interfaces — five of them for Olympique Lyonnais, then a talent-matching product. Freelance on all sorts of things since, shipping my own apps from Tokyo.
I build web interfaces, and I have done it long enough to care about the parts around them: the business problem, the data model, the release. I started at Olympique Lyonnais as an apprentice and left five years later as project manager and front-end developer, having shipped the club's data visualisation, live match and membership tools.

Every answer lands in a shared index, so the next person asking about that passage gets it instantly.
A self-hosted "Product OS": the PM agent that turns a scattered stream of feedback into a roadmap you can reason about. Feedback comes in raw, comes out sorted, linked to features and shaped into Shape Up bets. Zero egress, single SQLite file, one process.
