VLESS/XRay VPN sold through a Telegram bot (aiogram): plans, promos, referrals, refunds, Platega QR payments, in-bot admin with analytics. Web cabinet on React + FastAPI (JWT, Telegram Login). Remnawave is the only third-party piece (panel, config distribution, user DB); nodes run remnanode + Cloudflare WARP. The fleet is managed by a custom CLI over Ansible: one-command node bootstrap, rolling updates, DNAT front-relays, backups, healthchecks.
Short-form video farm promoting Zynerio VPN. Any source (YouTube channel/video or local files) is fetched by yt-dlp with bot-wall bypass and transcribed by faster-whisper large-v3 on GPU with word-level timings. A local LLM (Ollama) picks viral moments, verifies story boundaries and refines cuts by waveform. FFmpeg renders 9:16 blur-pad clips with word-by-word pop-in subtitles (libass), a censorship filter, programmatically rendered animated banners, and per-platform uniqueness packs (background, speed, crop jitter, mirror) for TikTok / Reels / Shorts. Jobs run as an on-disk state machine with a FIFO scheduler and a ledger deduping already-cut scenes.
Drawing app built with Flutter and a high-performance custom canvas engine. Features intuitive brush controls, opacity layering, dynamic color palettes, and seamless in-app purchases via RevenueCat & StoreKit.

PythonAbout & Experience
Background
I started my engineering path in game development (Unity), building interactive mechanics, custom rendering, and high-framerate visuals. That mindset naturally evolved into full-stack product engineering: today I build complete systems across the entire lifecycle — from high-performance Flutter mobile apps with Live2D character animation, real-time voice, vision AI, and in-app subscriptions, to GPU-powered Python automation farms (Whisper, LLMs, FFmpeg), scalable backends (FastAPI, PostgreSQL), Telegram bots, and automated server fleets managed via Ansible.
I love building products that solve real problems, work without friction, and scale cleanly. Async-first by default, comfortable owning features end-to-end, and focused on shipping working software to production.

What I do
Flutter & Mobile Products
Full-cycle mobile development: custom high-performance canvas engines, AI-powered interactive companions (Live2D, real-time lip-sync, TTS/STT, computer vision), in-app purchases & subscriptions (StoreKit, RevenueCat), push notifications, WebSocket streaming, and App Store releases.
Python, AI & Automation Pipelines
Backend systems and autonomous media farms: GPU-accelerated video/audio processing pipelines (Whisper large-v3, FFmpeg 9:16 rendering, Ollama LLM scripting), Telegram bots with analytics (aiogram 3), FastAPI microservices, and automated server fleet provisioning (Ansible, Docker, VLESS/XRay).
