Full-stack developer in Seoul, building web apps, AI assistants and learning tools.
I build web applications end to end — NestJS and GraphQL APIs, Next.js and React frontends, Docker deployments on Linux servers — and add AI to them: image classifiers and retrieval-augmented chat assistants. I also build learning tools, including a Korean-language Telegram bot for Uzbek speakers. M.S. in AI Business, Seoul Media Institute of Technology (2026).
Open to full-time full-stack, backend or AI-application roles in Korea.
