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.

Selected work
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.
Interactive chat companion with animated Live2D characters: real-time lip-sync, TTS/STT voice dialogue, vision, and image generation. Full mobile production stack: in-app subscriptions, ads, analytics, push notifications, and WebSocket streaming.
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 design and ship production-ready async backends with FastAPI, Telegram bots, and distributed data processing systems. I handle features end-to-end: from PostgreSQL database schemas, indexing, and Redis caching to CI/CD pipelines, Docker containerization, and AI model orchestration.
Experienced in building GPU media pipelines (Whisper large-v3, FFmpeg NVENC, local LLMs) and automated server fleets. Async-first by default, comfortable owning services without micromanagement, and focused on shipping working software to production.

What I do
FastAPI, Backend & Microservices
Async REST APIs and WebSockets, transactional integrity with row-level locks in PostgreSQL to prevent double-spending, Redis caching, Alembic migrations, third-party API integrations, and billing webhooks.
AI, Media Pipelines & Automation
GPU-accelerated video/audio processing pipelines (Whisper large-v3, FFmpeg NVENC, dynamic ASS subtitles), Telegram bots with analytics (aiogram 3), async data scrapers, and automated server fleets via Ansible.
