Since 2024, David has been the Head of the Legislative, Legal, and Methodological Unit in the Department of Strategies, Law, and Public Investment Support at the Ministry of Regional Development. He has been deeply involved in public procurement for over 20 years. He previously worked at the same ministry in 2005 and 2006, during which time he co-authored the former Act No. 137/2006 Coll., on Public Procurement. From 2007 to 2021, he was a partner and later a cooperating attorney at a leading law firm specializing in public procurement. Driven by his passion for improving public procurement legislation and methodology, he seized the opportunity to return to the Ministry, initially joining the European and International Law Division.
