AI-powered language flashcard app for iOS. Users describe any theme ("Coffee and tea", "Driving exam") and the app instantly generates a custom deck via Google Gemini. Features a progressive 3-level vocabulary system (beginner → intermediate → advanced) with mastery-based unlocking, SM-2/FSRS spaced repetition with Again/Hard/Good/Easy ratings, offline-first SQLite storage, bilingual audio examples, smart daily reminders, and a freemium model (RevenueCat) gating unlimited decks and advanced levels.
Built with React Native (Expo), TypeScript, SQLite, Supabase, Google Gemini, RevenueCat.

A health-tracking Android app for logging blood pressure, oxygen, pulse, glucose and
weight — designed for elderly users first. Oversized one-digit-at-a-time keypad,
high-contrast readings, and a one-tap printable report their doctor can actually read.
Medication list that keeps withdrawn drugs visible in red instead of hiding them, so
nobody takes one by mistake.
Offline-first: the database lives on the device and never leaves it unless the user
syncs it to their own LAN server. Built with Expo/React Native in strict TypeScript
across 15 languages, with speech input, a marketing site in Astro on Cloudflare Pages
behind a hash-pinned CSP, and a Hono + SQLite sync server with last-write-wins
reconciliation.
