Rockstar🎓
Top SchoolXiaochong Wei is a software engineer based in Old Toronto with seven years of experience building high-performance systems across industry and academia. He has production and open-source experience deploying observability tooling and contributing to Presto and Velox while shipping features at scale for companies including Uber and ByteDance. A MASc graduate from University of Toronto with top-tier undergraduate performance from Wuhan University, he blends rigorous research experience in DSRG with practical Android and backend engineering. Xiaochong has taught core systems and programming courses, reflecting strong communication skills and a knack for distilling complex concepts. Colleagues would describe him as driven by a “do it best or not at all” mindset—ambitious, detail-oriented, and comfortable moving between research, open source, and product engineering. An unexpected detail: his GitHub bio’s tongue-in-cheek “Rent here for $22 per month” hints at a pragmatic sense of humor behind a serious technical profile.
