Rockstar🎓
Top SchoolMehmet Yılmaz is a Senior Software Engineer with a decade of experience building web, enterprise and cloud-native systems, currently advancing Citus as part of Azure Cosmos DB for PostgreSQL at Microsoft. He blends backend expertise in distributed databases and PostgreSQL internals with full‑stack experience from IoT and enterprise projects, having implemented microservices, CI/CD pipelines and front-end interfaces across Siemens, GE Digital and banking platforms. Mehmet’s open-source contributions to the high-profile citusdata/citus project include fixes for race conditions, PG17 API compatibility and regression tests—work that reflects deep knowledge of database internals and production reliability. Comfortable in agile teams, he pairs strong analytical skills with patience and a continuous learning mindset, and holds both a Computer Engineering degree and an MBA. A less obvious strength is his long-standing operational background—from Oracle RAC and backup systems to device-level IoT software—that informs pragmatic, resilient design choices.
