About me.
Hi, I’m Zerui Yang. You might know me as Similarityoung.
I’m a backend developer and an Apache Dubbo Committer. I work mainly in Go, with an interest in RPC, gateways, and distributed systems.
Much of my work happens in open source. In Dubbo-go-Pixiu, I’ve contributed to gRPC streaming, MCP integration, authorization, and service discovery. I also explore Java, Python, and agent workflows through projects.
This site brings together what I build, learn, and think about. The notes are working notes: a record of questions and the understanding that comes from following them.
