About Me

CTO of DingTalk, Alibaba | Hangzhou & Seattle

My name is Hugo Zhu (朱鸿). I’m currently the CTO of DingTalk at Alibaba, based in Hangzhou and Seattle.

This blog is where I share my thoughts and hands-on experience in:

  • AI / LLM engineering — fine-tuning, inference optimization, AI agent workflows
  • Networking & infrastructure — Tailscale, OpenWrt, Docker, Kubernetes
  • Raspberry Pi & IoT — GPIO programming, home automation, edge computing
  • System architecture & DevOps — CI/CD, observability, cloud-native

I’m a polyglot engineer who has written production code in Go, Python, C, and AppleScript. On GitHub (github.com/hugozhu) you can find projects like godingtalk (DingTalk Open API Go SDK), WiringPi-Go (Raspberry Pi GPIO bindings), and various blog tooling.
