Niko on Data — Engineering, Writing & Consulting

Hi, my name is

Nikolai Potapov.
I build data systems.

I build and optimize modern data platforms: fast transformations, reliable storage, pragmatic orchestration, and production-grade observability — with a strong focus on Polars, ClickHouse, Delta Lake, and OSS-first architecture.
