Summary
🤩
Rockstar🎓
Top SchoolShlomi Noach is a seasoned software engineer and database specialist with 13+ years designing high-availability, distributed database systems and infrastructure. Now at PlanetScale, he helps drive Vitess and pioneered native, declarative schema migrations and branching for cloud databases. Previously at GitHub and Booking.com he authored widely used open-source tools—most notably orchestrator and gh-ost—which power MySQL topology management and low-impact online schema changes in production at major companies. He blends deep systems programming (Go, C/C++, Java) with operational experience in automation, throttling and recoverability, and is a frequent speaker and MySQL community award winner. A less obvious thread through his career is a focus on enabling safe, reversible change: from orchestration to schema workflows—making risky operations predictable and automatable.
