Experienced data engineer with a bachelor’s degree in mathematics. I build data platforms, pipelines and admin databases. From time to time I contribute to open source. My favorite topics are SQL generation and DataFrame semantics.
I also have one small Pomeranian Spitz. Pushing him to do something he does not want to is much harder than everything listed above.
