Hi, I’m Hancic — a full-stack software engineer based in Beijing, China.

What I do

  • Backend / data / operations, with Python and Rust as my main languages
  • Write mostly in an AI-driven, practical way — comfortable across tooling and stacks
  • Interested in distributed systems, trading systems / quant, and self-hosting

This blog

Engineering notes in English for a global audience: systems design, infrastructure, and the occasional opinion on tooling. The Chinese blog lives at blog.hancic.site and covers similar topics in Chinese.

Elsewhere

Off the keyboard

Fitness, swimming, hiking, badminton, reading history & fiction. Also tinkering with Raspberry Pi, ESP32, and sensors.
