Founder · Full-stack builder

Kayra,
building quietly
in Milan.

I build fast, opinionated products at the intersection of AI, UX, and everyday life. Currently shipping consumer and prosumer tools that replace Google Docs workflows, track inflation, and help people say things they can't.

Open to collaborations and angel cheques.
