Hi there 👋

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

  • ⛁ I’m currently working on BBoxDB - a distributed key-bounding-box-value database for multi-dimensional data implemented from scratch.

  • 🔭 In addition, I work actively on PostgreSQL Lock Tracer - a tool collection to gain deep insights into PostgreSQL's locking activities and troubleshoot performance-related issues.

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