Autonomous short-video farm: any source → viral clips for TikTok / Reels / Shorts

Ready clip: hook title, karaoke subs & animated banner
Ready clip from another source: subs & banner overlay
Ready clip: per-platform render for TikTok / Reels / Shorts

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.

About & 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).

Start with a fast paid pilot

2–3 days with a fixed price and clear scope to test team chemistry, build a high-impact feature or prototype, and seamlessly transition into a retainer or full contract.
