Developed and delivered a file-based filtering feature for call context queries in the flowr-analysis/flowr repository, focusing on enhancing the precision and efficiency of backend analysis workflows. The implementation introduced new configuration options that allow results to be restricted based on the file location of calls, enabling more targeted and data-driven debugging. Addressed potential issues by improving the handling of undefined file attributes, which increased the robustness of the query system and prevented failures during filtered analyses. The work was carried out using TypeScript and centered on API and backend development, aligning closely with project goals to improve traceability and workflow efficiency.
