Diana Villalvazo contributed to multiple open edX frontend repositories, focusing on internationalization modernization, frontend refactoring, and testing infrastructure upgrades. She migrated legacy injectIntl patterns to useIntl hooks across apps like frontend-app-account and frontend-app-authn, streamlining translation workflows and improving maintainability. In frontend-app-learner-dashboard, Diana enhanced accessibility, configurability, and code clarity by refactoring UI components, updating state management with React and Redux, and standardizing URL parameter handling using JavaScript and TypeScript. She also modernized test suites by adopting React Testing Library and Jest, reducing technical debt and improving test reliability. Her work enabled faster, safer feature delivery and consistent user experiences.

September 2025 monthly summary: Key internationalization refactors in the account app and test-suite modernization in ora-grading delivered cleaner code, stronger translation workflows, and more reliable tests. These efforts reduce localization maintenance costs, minimize translation-related risks, and support faster, higher-quality feature delivery across repositories.

2025-08 monthly summary: Delivered widespread internationalization modernization by migrating from injectIntl to useIntl across six open edX frontend apps, reinforcing a modern React i18n pattern and consistent translation access. The work spanned authn, account, learner-record, discussions, enterprise-public-catalog, and admin-portal, with corresponding test updates to reflect useIntl usage. In addition, added comprehensive test coverage for Camera.getSizeFactor to validate image scaling across large, small, and medium resolutions. No production bugs were fixed this month; the refactors reduce technical debt, improve maintainability, and standardize i18n usage, enabling faster, safer feature delivery and a consistent user experience. Technologies/skills demonstrated include React hooks (useIntl), i18n modernization, large-scale refactoring, and test development for UI components.

May 2025: Focused on delivering high-value frontend improvements for the learner dashboard with emphasis on accessibility, configurability, and maintainability. Key work includes UI semantics fixes, a new config-driven Discover New tab visibility flag, advertised start date on course cards, a codebase refactor to native URLSearchParams, and comprehensive cleanup of the LearnerDashboardHeader. Tests were updated to reflect UI and behavior changes, contributing to regression safety and faster future iterations. Overall impact: improved user experience, cleaner code, and more predictable UI behavior across environments.
