Engineer

Fifteen years writing backends and the infrastructure underneath. Fluent in Node.js / TypeScript, Python, Ruby on Rails, and Java — and equally at home with Kubernetes, Terraform, and CI/CD across AWS, GCP, and the Chinese cloud. Drawn to microservices, real-time pipelines, and LLM integration.

Side projects

Paw-San — a small iOS app for learning Japanese vocabulary, one word at a time. No streaks, no leaderboards.

Vibeband — an ambient sound generator that runs in your terminal. Written in Rust, powered by ElevenLabs.

Learner of Japanese

I've been chipping away at Japanese for a while now. Paw-San came out of that — a tool I wanted for myself. 言葉 at a time.

Currently

Open to senior backend roles. Remote, China-based, bilingual English / 中文. Particularly interested in real-time systems, payments, and AI tooling.

The best way to reach me is by email.
