Rockstar🎓
Top SchoolAlex Santamaura is a Senior Software Engineer with seven years of experience building backend systems and full-stack features across startups and mid-size companies, currently contributing to Zocdoc from New York. An electrical engineering graduate from the University of Waterloo, he brings an embedded-systems sensibility to cloud-native work, having made notable contributions to CockroachDB’s SQL layer and observability features that improved diagnostics and replication reporting. He’s comfortable across the stack—C#/ .NET, React/Redux, and distributed databases—and has shipped production features in healthcare, events, and media domains. Alex pairs rigorous systems thinking with practical product focus, often surfacing operational improvements (like privileged SHOW RANGES access and probe_ranges diagnostics) that make large distributed systems easier to operate.
