Developed a deterministic, sortable Process Instances table for the sartography/spiff-arena repository, focusing on enhancing data exploration and decision-making for users. Leveraging React and TypeScript, the solution introduced sortable headers for key columns such as end_in_seconds, id, and status, while maintaining non-sortable columns as plain headers for clarity. The implementation featured a deterministic id-based tiebreaker to ensure stable ordering and consistent pagination across pages. Integration with backend report metadata order_by enabled reliable and consistent data retrieval. All changes were thoroughly tested using continuous integration workflows, reflecting a methodical approach to front end development and robust feature delivery.
