Rockstar🎓
Top SchoolNils Dijk is a Principal Software Engineer based in Amsterdam with 15 years of experience building and optimizing distributed systems and databases. He has driven development of the Citus extension for PostgreSQL through roles at Citus Data and Microsoft, contributing deep database-internals work such as text search propagation, role reference handling for worker transport, and crash recovery fixes for columnar data. His background spans high-scale backend engineering at companies like Uber and Bottlenose, plus early automation projects for broadcast systems, giving him a practical blend of production reliability and systems design. Known for hands-on contributions to a widely used open-source distributed Postgres project, he combines low-level database expertise with architect-level thinking to ship resilient, scalable data platforms. An often-overlooked strength is his long-term focus on operational concerns—DBA tasks and recovery hardening—that keep complex systems running in the real world.
