@printfcoder/Backend & platform engineer/Shenzhen, China
I build backend platforms and the infrastructure around them — service frameworks, resource-access layers, observability, and stability systems. Most of the past decade went into making "it works" become "it stays working at scale."
These days I work on Peers Touch, a decentralized social network with built-in AI agents: peer-to-peer, self-hostable, with people owning their social data and connections. Earlier I ran the Go-Micro China & Stack-RPC tutorials, a Chinese-language Go microservice guide that grew into a sizable community.
