For the past 4+ years, I've been building full-stack applications with Node.js, React, and TypeScript — but my real focus has been video processing and real-time streaming. I've built a complete HLS streaming service from scratch: GPU-accelerated transcoding with FFmpeg, WebRTC signaling, and AI voice integrations (STT/TTS/LLM). I also worked on a real-time messaging platform serving 200+ daily users, where I optimized API performance and reduced storage costs by 60%. My open-source video project reflects what I enjoy most: solving complex media challenges and making video accessible. I'm now looking for a remote role where I can continue building video infrastructure and media products, ideally as a Video Engineer or Full-Stack Engineer in a streaming team.
