Olszewski

I build AI systems that show their work.

I own product and technical problems end to end — from a vague requirement, through architecture and implementation, to running it in production.

AIONA
iOS app · Consumer health & longevity
AI-powered longevity science, in your pocket.
Snap a photo of a meal and AIONA’s vision AI breaks it down into ingredients, macros and a daily Longevity Score across five health pillars. Then its AI advisor explains the score and coaches you on what to eat next, grounded in your own history.
Built end to end: a contract-first React Native, Go and Python stack with explicit system boundaries, AI-assisted implementation and production ownership.
