Developed a robust Windows data-clear feature for the tinyhumansai/openhuman repository, focusing on improving error handling and user guidance during app data resets. The solution detects when data files are locked by other processes and provides actionable messaging directly in the user interface, reducing friction for end users. Leveraging Node and React for both back end and front end development, the work included comprehensive testing to ensure messaging accuracy and reliability. The approach emphasized test-driven development and commit-driven workflows, resulting in a more dependable Windows data reset process and improved traceability for future maintenance and developer collaboration within the project.
