Rockstar🎓
Top SchoolAhmet Başak is an engineer with 11 years of experience building and leading teams that deliver scalable cloud-native database services, most recently managing the Azure Cosmos DB for PostgreSQL (Hyperscale/Citus) team at Microsoft. He combines deep backend and database expertise—contributing substantial fixes and features to the high-profile open-source Citus extension for PostgreSQL—with practical cloud operations experience on Azure and AWS. A Bilkent alumnus with an MSc in Computer Graphics, he bridges system-level distributed databases and simulation/graphics tooling, and maintains hands-on fluency in Ruby, Postgres, and game engines like Godot and Unity. Known for clarifying tricky planner and UDF behaviors in Citus, he brings both feature development and production DBA instincts to managed service delivery. Now at Ubicloud, he continues to apply that hybrid developer-operator perspective to build resilient, scalable systems from the kernel of PostgreSQL up to managed cloud services.
