Bowen Han.
Full Stack Developer, Agentic
California, USA
Passionate full-stack engineer with 9+ years of experience building and shipping production web applications — from consumer-facing tools to distributed AI-powered backend systems. Specialized in React/Redux, TypeScript, Next.js, Python, and SQL/NoSQL databases, with a strong focus on clean architecture, responsive UI, and scalable API design. Recent work includes Pomometer, a serverless productivity app (Next.js + Cloudflare Workers + Google Tasks sync, hundreds of DAU), and Call Buddy, a real-time VOIP agent that autonomously handles phone calls using a VAD → ASR → LLM → TTS pipeline. Also contributed CUDA kernel optimizations merged into llama.cpp, improving inference throughput by 35%. Comfortable across the full stack — from pixel-perfect frontends to gRPC microservices and Kubernetes deployments. Passionate about building things that actually ship and get used.
