Worked on the duckduckgo/privacy-configuration repository to implement the Set Default Prompts feature for Windows, addressing a missing override and correcting formatting to ensure reliable default prompt behavior. Focused on front-end development using JavaScript, the work enhanced Windows user experience parity and reduced the risk of regression by aligning functionality with platform standards. The approach emphasized code maintainability and repository consistency, with targeted Windows-specific fixes and thorough end-to-end validation. By enabling the set as default prompts capability, the contribution laid the foundation for improved cross-platform support and future enhancements, demonstrating attention to both technical detail and business value.
