His background spans founding a startup, building data lakes, and contributions at AWS and Nitro, reflecting both product-minded engineering and operational depth. Diego is an active open-source contributor focused on performance: his work on an in-memory TTL cache added generics, expiration callbacks and a priority-queue refactor to optimize expiration handling. Equally comfortable in systems and application layers, he pairs pragmatic leadership with a hobbyist’s curiosity in programming and photography.
