Marek Kovac is a Senior Privacy Lead and Vaix Data Protection Officer at Sportradar. Colleagues describe him as "Marek was student in my tutorials of International Commercial Law in 2018. I was impressed with his methodic dedication to his studies. He wrote a good research paper on payment mechanisms and smart contracts and was invited by the coordinator of the course and myself to present such a paper in a student conference on the future of international commercial law. He did a serious presentation, and fully met our high standards and expectations. In the capacity of reviewer of his Master thesis, I was also happy to testify that he took such an academic endeavour seriously and thus succeeded in such a task. Due to this very positive impression I had of Marek as a Master student, I followed his promissing international career in Vienna and invited him to co-teach one of my tutorials of International Business Law at the Hasselt University. This happened recently and he did very well. His presentation on smart contracts and letters of credit, which tackled also privacy and data protection issues, was an important component in my students' syllabus, at the light of the new developments in the field of IBL. He was also extremely available in answering all the questions from students, which showed his professionalism and dedication to the tasks he takes upon. Overall, I am very impressed with Marek as a former student and as a young professional and am confident that his dedication to his projects and professionalism will take him far in his career, for which I wish him the very best." and "When Marek came into our team, he had to learn a whole new set of skills. I was amazed at how quickly he took to the work and learned. He was very good at advising internal clients and managing casework. His analytical skills were exemplary and his advice was always well set out and clear to understand for less knowledgable clients. He presented well in meetings and provided excellent training sessions for stakeholders. His humour helps navigate difficult situations with utmost diplomacy. He was an excellent team player and very well liked by the team. When he left for a new role, he was sorely missed. I wish him the very best for his future."
