I started my IT carrier as Engineer at national telecommunication Ukrainian networks. Than I worked as web full stack developer and IT manager for 10 years. After relocation to Poland at 2012, I continued my carrier path at Clicktrans company which represents one of the biggest transport marketplaces in Europe. Currently I am taking the position of CTO&System Architect at Clicktrans. My work is concentrated around architecture for complex systems, using ML for solving transport problems, big data sets analysis, search & recommendations systems.
