Krzysztof Tabak

My name is Krzysztof Tabak and I work as an Application Architect at Circle K Business Centre Poland. I finished engineering studies in Computer Science at the Military University of Technology in Warsaw, and then master's studies in Management at the University of Warsaw. I began my adventure with IT after my second year of engineering studies as an intern at Comarch, developing loyalty systems. However, the desire to develop and learn about the possibilities of the industry quickly gave my career a boost. From Comarch, I moved as a Java programmer to PIT Radwar S.A., where I participated in a project implemented for NATO. Then, I programmed at one of the largest technology companies in Poland - Allegro, where I had the opportunity to experience working in an environment of several thousand microservices creating a marketplace known to everyone. Finally, I moved to Circle K, where I work to this day, developing systems for managing fleet cards and purchasing fuels. As an Application Architect, I combine the role of a senior Java programmer and an architect at the application level, developing modern backend products using cloud technologies.
