Full-stack mobile engineer. Founder of icodex studio.
I build mobile apps and run them after launch: Postgres schema, serverless backend, native auth, payments, the React Native layer and the store release process. Built solo, end to end.
Bodica teaches body language through structured lessons, quizzes and AI photo analysis. Photos are analyzed by a Supabase Edge Function that calls Gemini, so keys and prompts never reach the client. Users sign in with Apple, Google or email OTP, tokens live in hardware-encrypted storage, and token refresh is serialized behind a mutex. Subscriptions run through RevenueCat on StoreKit 2 with server-side webhook validation, push notifications use actionable categories, and analytics only run after GDPR consent.

Radora helps you learn English by reading. A spaced repetition engine schedules every word server-side, so progress is decided by the backend rather than the client, with XP, levels and streaks on top. The data layer is local-first: screens render from cache on cold start, and writes that fail on a bad network replay when it comes back. Premium content is gated by Row Level Security rather than a client-side check. Localized in English, Spanish and Turkish, with a Next.js admin panel on Vercel.

icodex studio takes a small number of client projects: mobile apps built with React Native, Expo and Supabase, from schema design to store release. If you need the whole stack owned by one person, write to me.
