My name is Nan Xiao, a system software / performance engineer, and have more than 10 years experience in software architecture & development: from embedded system to server box. I am especially enthusiastic in technologies related to computer infrastructure, such as Operating System kernel, concurrent programming, debugging, performance tuning, etc. I like to keep studying and trying new stuff which I haven’t touched before, e.g., in the past 2015, I focused on Go and FreeBSD, and now I think I should make my hands dirty in Rust and eBPF this year. I also love Free / Open Source software projects, and have done some contributions to them. You can contact me: nan#chinadtrace.org (please replace ‘#’ with ‘@’).
