About
I’m Raymond — Yu-Chuan Hung — a data engineer based in Taipei.
I currently work at Garmin Taiwan on streaming pipelines and lakehouses (Apache Iceberg + Nessie), with a growing amount of Rust on the side. Outside of work I contribute to a handful of Apache open-source projects when I can.
This blog is where I write things down so I can find them again later — and so anyone else hitting the same problems can get unstuck a little faster.
