I am a developer advocate at DuckDB Labs, the company behind DuckDB. I edit the documentation and the blog, give talks and run interesting benchmark experiments. I also co-organize DuckCons and DuckDB meetups.

Outside of my day job, I am a contributor of the Linked Data Benchmark Council (LDBC), a non-profit organization that promotes the use of graph data management technology and defines TPC-style graph database benchmarks.

Previously, I spent a decade in academia. I obtained my PhD in software engineering at the Critical Systems Research Group of TU Budapest, followed by a 3-year stint as a post-doctoral researcher at the Database Architectures group of CWI Amsterdam. My research focused on graph queries, graph analytics, and benchmarks.

Besides the news on what I’ve been up to, I share some personal notes on this site.
