July 2025 highlights for kobotoolbox/kpi focused on user experience, maintainability, and performance. Key features delivered include: (1) User-facing error messaging improvements for the UI table view and forms, replacing raw HTML errors with friendly messages and distinguishing 500 vs non-500 form-state errors to aid diagnosis and reduce support load; (2) Code modernization by bulk-decaffeinating FormBuilder from CoffeeScript to JavaScript to modernize the codebase while preserving functionality; (3) Wording clarity for Validation Criteria and Skip Logic in the Form Builder, reducing user confusion and misconfiguration; (4) Export enhancements with a date-range filter to reduce backend memory usage and improve export performance; (5) UI polish of the Form version history (Deployed badge, date alignment, and clone icon placement) to improve usability and discoverability of form history. These changes were implemented through a series of targeted commits, enabling faster issue triage, easier future maintenance, and more efficient data exports. Overall impact: improved user experience and reliability in data presentation, reduced server load and memory usage during exports, and a leaner, more maintainable frontend codebase. The work directly supports business value by reducing support overhead, speeding up troubleshooting, and enabling more efficient data workflows. Technologies/skills demonstrated: frontend error handling UX, UI copy clarity, CoffeeScript-to-JavaScript modernization, incremental refactoring, UI/UX polish, and performance optimization via export filtering, all with careful attention to regression safety and traceability through commit-level changes.

June 2025 — kobotoolbox/kpi: Implemented a targeted permission guard for the Delete media files button in bulk actions. The UI is now visible only to users with change_submissions or higher, fixing a gap where delete_submissions-only roles could see and potentially use the button. This security/UX improvement reduces risk of unintended deletions and aligns with RBAC policy. The work was tracked under DEV-5838 with commit cf1e0067aa3bc04ee64e1fe1e9d3278fbd85bfc8, and completes the bug fix without impacting existing features.
