PROFILE
Filip Michalski
Worked on the TouK/nussknacker repository, delivering user-facing features and critical reliability improvements across backend and frontend systems. Built and integrated sticky notes into the scenario graph, enabling collaborative annotations with persistent storage in JSON and robust import flows. Enhanced data safety by adding deletion confirmation dialogs and made note limits configurable for greater flexibility. Addressed complex bugs, such as parallel union node invocation, through targeted fixes and expanded test coverage. Contributed geometric helper functions to strengthen data processing pipelines. Leveraged Scala, TypeScript, and React, applying skills in API design, backend development, and testing to improve maintainability and user experience.
