Lethbridge, Alberta, Canada
Summary
🤩
RockstarMorgan Tocker is a seasoned software engineer with 12 years of experience specializing in databases and MySQL-compatible systems, currently contributing to Cash Databases at Block from Lethbridge, Alberta. He has a deep backend and database engineering pedigree demonstrated by significant open-source work on high-profile projects like TiDB, Vitess, and gh-ost—adding MySQL-compatible SQL features, fast/instant DDL support, and compatibility fixes. His career blends hands-on engineering, product and community roles (including maintainer and product manager positions at PingCAP and Vitess), giving him rare visibility into both developer experience and production-scale operational concerns. Comfortable across the full stack, he also contributes frontend/documentation improvements and build tooling, showing attention to usability as well as internals. Notably, his contributions often target subtle compatibility and upgrade paths—character sets, collations, grants and sysvars—areas that materially reduce migration friction for large MySQL deployments.
