During April 2026, contributed to the Expensify/k2-extension repository by addressing a critical issue affecting the GitHub PR merge workflow. Focused on front end development using JavaScript, the work involved updating DOM selectors to adapt to recent changes in GitHub’s interface, ensuring the HOLD merge button was correctly disabled when required.

The solution included thorough regression testing across multiple pull requests to verify stability and compatibility. Emphasis was placed on reliable DOM manipulation and maintaining seamless UI interactions as GitHub’s underlying structure evolved.
