Developed the Inline Notes feature for the actualbudget/actual repository, enabling users to attach contextual notes directly to individual monthly budget cells for improved decision-making. The work involved front end development using React and TypeScript, with a focus on enhancing the budgeting interface and supporting a robust mobile experience. UI and UX refinements included updated modal layouts and adjustments to the mobile budget menu, while maintainability was addressed through automated testing and alignment with visual regression testing workflows. Collaborative efforts included co-authoring pull requests and participating in cross-team reviews to improve documentation, code consistency, and overall feature integration within the codebase.
