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

- ⛁ I’m currently working on [BBoxDB](https://bboxdb.org) - a distributed key-bounding-box-value database for multi-dimensional data implemented from scratch. 

- 🔭 In addition, I work actively on [PostgreSQL Lock Tracer](https://github.com/jnidzwetzki/pg-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](https://jnidzwetzki.github.io/about/)

- ⚡ Fun fact: My first installed Linux Distribution was a SuSE 6.1 (Kernel 2.2.6) in 1999, and my first computer was a Pentium 1 with 100 MHz and 16 MB RAM running Windows 95.
