Hi, I'm Huaijin

Rust · Observability · Data Systems · AI Infrastructure

Building practical open-source infrastructure.

Currently

  • Working on OpenObserve
  • Contributing to Apache DataFusion
  • Learning deeper Rust systems programming
  • Exploring agent development and AI infrastructure

About

I enjoy building infrastructure that is reliable in production and easy to reason about.

Recently, I have been spending more time around observability systems, query execution, telemetry pipelines, backend performance, agent development, and AI infrastructure.

Open Source

Projects I follow and contribute to:

Keep systems simple. Make behavior visible.
