I am Jan, a software developer and computer scientist with a focus on (distributed) databases.

  • ⛁ I’m currently working on PostgreSQL Lock Tracer - a tool collection to gain deep insights into PostgreSQL's locking activities and troubleshoot performance-related issues.

  • 🎓 Previously, I was active in database research and have created systems like BBoxDB or Distributed SECONDO

  • 🌍 You can find more about me and my projects on my website
