Top SchoolRicardo De Cillo is a Senior Software Engineer with 13 years of experience building and operating highly available, cost-conscious data systems.

Comfortable across backend stacks and distributed systems, he favors simple, operable solutions and pragmatic technology choices that avoid unnecessary operational burden. Currently at Indeed, he continues to focus on reliability and incident investigation while drawing on prior experience migrating monoliths to microservices and building event-driven APIs like Nakadi.
