Flutter & Python engineer. I take products from idea to release: mobile apps on Flutter, and automation pipelines in Python. Async-first — text over calls, written English only.
Flutter apps
- ai-chan-flutter — AI companion chat: native Live2D rendering on Metal, real-time lip-sync, full voice pipeline (STT → LLM → TTS), multi-LLM with fallback. Shipped to the App Store.
- coloring-book — coloring app with a custom canvas engine and CV-based accuracy scoring; StoreKit subscriptions, AppLovin MAX mediation. On the App Store.
Python automation
- video-conveyor — automated short-video pipeline: Whisper transcription, LLM clip selection, FFmpeg rendering with karaoke subtitles, GPU orchestration on constrained hardware.

Own product

Background: 5 years of shipping, previously Unity/C# (mobile games, Telegram mini-apps with TON integration) — that history lives in the older repos below.
