I’m Çağrı, a database systems engineer based in the Netherlands.
I work at Adyen, where my days usually revolve around keeping large PostgreSQL clusters reliable, fast, and mostly calm while trying to automate everything that can go wrong twice.

Over the years I’ve worked across PostgreSQL, MySQL, Oracle, and SQL Server, building systems that stay up when they really shouldn’t. I love the intersection of performance, reliability, and automation figuring out how databases behave under stress and how we can make them heal themselves a little faster next time.

Outside work, I enjoy travelling , discovering and playing games online(PC)/offline(boardgames)
