Summary
🤩
Rockstar🎓
Top SchoolRui Mo is a software engineer with 7 years of experience specializing in query engines, databases, and native computing, currently working on Apache Gluten and Velox. Based in Leinster, Ireland, he has contributed to production-grade C++ and JVM interoperability by building Substrait-to-Velox conversion layers and hardening Gluten’s Arrow integration to offload SQL execution to native engines. At Intel and now IBM, he focused on backend data execution, codebase refactoring, dependency cleanup, and improving build and documentation workflows—skills that reduce technical debt and accelerate adoption. Rui’s work on two high-impact open-source projects shows a pragmatic balance of systems design and hands-on engineering, including enabling decimal type support and streamlining parsing pipelines. He holds a master’s from Shanghai Jiao Tong University and brings both academic rigor and practical engineering discipline to high-performance data systems.
