Leading engineering for Postgres on Azure with Affan Dar
What’s it like to lead Postgres engineering at a cloud giant like Microsoft Azure? In this episode of Talking Postgres, host Claire Giordano chats with Affan Dar, VP of Engineering for Postgres at Microsoft. Affan’s team is behind the Azure Database for PostgreSQL managed service and also contributes extensively to the upstream Postgres open-source project. Affan walks us through his career journey—from his first job as an embedded systems engineer, to navigating the shift between engineering and management, to leading one of the largest Postgres engineering teams in the world. He shares the strategy behind Microsoft’s investments into Postgres, explores how massive cloud fleets are influencing the future of Postgres, and shares what keeps him up at night.
