At MR73BIIO, I build data pipelines and automations for companies operating between Poland and Switzerland. I extract, transform, and load data from APIs, PDFs, and CSVs into clean archives, with checks that verify each step before reporting success.
For GIS data, I found all 160 injected test errors in Polish administrative boundaries and brought three tree cadastres from Zurich, Vienna, and Berlin into one structure of 1,276,769 records. After 22 years in international transport and logistics operations, I now apply that operational experience to automation, data quality, and cross-border work.
