A quiet practice
of shipping.

I'm Gian — an engineer who's spent the last decade-plus shipping mobile, backend, and AI systems across fintech, health, esports, and e-commerce, and leading the teams that build them. I've been Head of Engineering; I write here about what that actually looks like, and about the systems I build myself.
