Jiří is constantly improving our ETL process. He builds databases and makes sure they are filled with the right data at the right time.

Dedicated to mastering R, Python and SQL on higher level than his colleagues dare to comprehend, he made it his professional mission to write clean code to uncover sometimes dirty secrets hidden in large datasets.

Some people are ashamed of their university years. Jiří is ashamed of sub-routines he wrote in C when he was 23. It's all right, though - those years are behind him and shame does not plague his beautiful mind anymore.
