I’m Jianyong Chen, a software engineer. I’m interested in edge computing, serverless, distributed systems, and performance optimization. I mostly write Go and C/C++, and also like Rust, Lua, Python, and JavaScript.
Here you’ll find:
- Blog posts: notes on performance, distributed systems, and low-level optimization.
- Projects: things I have built or contributed to.
- Photos: places I’ve been.
- Moments: passing thoughts and fragments I want to keep.
