01 / ABOUT

Two decades of building, from telecom to LLM infrastructure

edu: Chengdu University of IT · class of 2004

I'm a software engineer and technical leader based in Chengdu, China. I've shipped telecom portals for Sichuan Telecom, scaled sports-community platforms and fitness hardware as Tech Leader at Codoon, co-founded a blockchain-based smart logistics startup, and since 2020 work as an independent freelancer on AI systems.

My current focus is high-performance infrastructure in Rust: LLM inference routing, RDMA storage engines, distributed configuration management and real-time messaging. I also write about document-driven development for AI coding agents and build long-term memory plugins that make coding agents genuinely useful.

Technically bilingual — fluent in Rust, Python and TypeScript today; C#, Swift and Objective-C in a past life. I care about systems that are fast, observable and boringly reliable.
