Jan Kosmala

Engineering Manager for the Data team, OLX Group

He has been working there since 2014 and during that time he was a key engineer in various technological migrations. The latest migration was from Azure Analysis Services to Apache Kylin - he and his team were primarily responsible for migrating data between the two systems and enabling internal clients to work.
