Rockstar🎓
Top SchoolHenry Baba-weiss is a Principal Software Engineer in Seattle with 14 years of experience building compilers, runtimes, and distributed database systems. He combines deep systems expertise from roles at Microsoft (working on .NET Native, JIT testing tools like SuperPMI and SemanticDiff) with production distributed database work at Clustrix/MariaDB and PingCAP. At PingCAP he contributes to TiDB, a well-known cloud-native distributed SQL database, focusing on SQL planning, parser work, statement summary features, and query performance optimization. Henry has a strong low-level debugging and forensic background—diagnosing crashes from stack/memory dumps and improving binary-level tooling—that complements his high-level compiler and runtime design skills. He is comfortable across C, C#, and assembly-level analysis and has repeatedly delivered tooling and systems that make complex compiler and database behavior observable and reliable. Known for pragmatic engineering, he often moves correctness checks earlier in pipelines and builds infrastructure that scales both for developers and production systems.
