Sevastian Rakhimov
I take AI prototypes to production — live, paid and stable
Meet Sevastian
I build AI products that hold up outside the demo.
Co-founder and CTO of F/AI, an AI fitness trainer: 340,000+ users, 23,000 monthly actives, $8,000 MRR and 2,000+ paid subscriptions, live in both stores. Flutter and Swift on the front, Supabase and PostgreSQL underneath, LLM pipelines on LangGraph in between, and billing across the app stores plus direct web subscriptions. The user counter is public at fitgpt.pro/stats if you would rather check than take my word for it.
Before that, six years with a New York SaaS company — the first eighteen months of it as the only engineer.
What I am hired for is the unglamorous half: the prototype works, and now it needs auth, payments, error handling, observability, cost control and a deploy that does not wake anyone up.
12 years in software. Tbilisi, Georgia (UTC+4), fluent English, calls without a translator. Fixed price, 20-30 hours a week.
