Rockstar🎓
Top SchoolPekka Enberg is a founder and CTO with 19 years of deep systems and database engineering experience, currently leading Turso (Turso Database) while completing a Ph.D. at the University of Helsinki. He has a strong track record in high-performance back-end and OS-level work, from Linux kernel and OSv contributions to implementing CQL front-ends and schema management for ScyllaDB. Pekka repeatedly lands subtle correctness and performance fixes—integer overflow guards, precise numeric parsing, and optimized inlining—that reveal a meticulous, low-level engineering mindset. He’s built production-grade database features (jsonb, timediff, DROP handling) and improved WASM bindings for libSQL, bridging C APIs and JavaScript. Based in Espoo, Finland, he combines academic rigor with startup execution, shipping core database internals while steering product and architecture. An understated strength is his ability to move between systems programming and developer-facing APIs, making complex internals accessible and reliable.
