Rockstar🎓
Top SchoolEduardo O is a Staff Software Engineer specializing in datastores with over a decade of hands-on experience building and operating large-scale MySQL and PostgreSQL infrastructures. He has led reliability, automation and capacity initiatives at companies like Slack and Booking.com, delivering fleet-wide savings and dramatically reducing toil through sharding automation and schema-change tooling. A pragmatic backend engineer and database specialist, he’s contributed to prominent open-source projects such as Vitess and Orchestrator, improving transaction throttling and group-replication support for MySQL clustering and topology management. Eduardo combines systems-level expertise (Linux, virtualization, networking) with strong automation chops to turn operational pain points into self-healing platforms. He holds advanced degrees in physics and systems engineering, a background that surfaces in data-driven, analytical approaches to reliability problems. Colleagues describe him as results-oriented and endlessly curious, often finding efficiency gains that aren’t obvious until after they’re implemented.
