Juraj Dončević PhD is a teaching assistant at the Faculty of Electrical Engineering, University of Zagreb. He is currently employed at the Department of Applied Computing. In 2024, he defended his PhD thesis: "Extension of the mediator-wrapper architecture for heterogeneous data source integration by adding a mask".

His research is focused on software architecture, software design, data management, bidirectionalization and functional programming. He is currently working on Janus V2.0 and a library of BX lenses in C# (both projects are pending funding). Long-standing organizer of the Open Doors Day at FER for the Department of Applied Computing, promoting STEM to younger students. Proficient in multiple programming languages and techonologies.
