Summary

Senior🎓
Top SchoolYuxiang Chen is a Senior Software Engineer with deep expertise in query optimization and large-scale data infrastructure, currently at Databricks after leading core optimizer and execution work at ByteDance. He has a strong track record improving performance—examples include a late materialization change that delivered 20x speedups and rearchitecting Spark readers at LinkedIn with up to 95% read improvements. Trained at Carnegie Mellon (MS) and Shanghai Jiao Tong (BS), he blends systems research with production engineering across databases, distributed systems, and cloud platforms. He’s built production tooling like optimizer tracers, query replay frameworks, and plan-caching layers that reduce redundant work and simplify debugging. Known for turning research ideas into shipping features, he quietly maintains a pragmatic, utility-focused approach to engineering (his GitHub bio reads “移动打杂中,” hinting at a hands-on, get-things-done ethos).
