I’m Similarityoung, a backend engineer working mainly in Go and an Apache Dubbo committer. My work centers on RPC frameworks and gateways. These days I study agent development, and how the infrastructure beneath agents ought to be built. Most of what I know, I learned in open source.
feat:Became an Apache Dubbo committerHEAD
feat:Joined Xianyu Agent Infra
Building observability and diagnostics for AI-driven development pipelines.
feat:Joined OSPP on the Dubbo-go-Pixiu AI gateway
My work on Pixiu has since covered gRPC streaming, MCP integration, authorization, and service discovery.
AI can write the code, but I remain responsible for what it produces. So rather than taking large strides, I start from a small loop that closes end to end.
AI now produces more code than anyone can review line by line. Instead of reading all of it, I would confine it to narrow, well-defined interfaces and guard the output with verification that actually holds. Of everything here, I consider this the most important.
Doing this well means studying the design of good projects: learning to define and decompose problems, and knowing how to abstract and how to generalize. Each of these is a broad subject, and I am still learning.
This site collects what I build, learn, and think about. The notes are working notes: a record of questions, and of the understanding that comes from following them.
