March 2026 — PrairieLearn/PrairieLearn: Delivered Calculator UX enhancements with persistent history and accessibility, integrating assessment tools with the calculator and implementing a manual policy to suppress the default on-screen keyboard on touch devices to enable a custom keyboard. Major bugs fixed include data synchronization fixes for assessment tools, reliability improvements around localStorage, and font loading issues, with a transactional approach to synchronize assessments for data integrity. Overall impact: smoother, more accessible assessment experiences, reduced support overhead, and a stronger foundation for maintainable front-end and API integration. Technologies/skills demonstrated: TypeScript modernization of the calculator client, Drawer-based UI and Bootstrap styling, ARIA/accessibility improvements, compute-engine integration upgrades, SQL/schema updates, and resilient state management across sessions.

Month: 2025-10 — No new user-facing features released in tscircuit/eval. Primary focus was stabilizing the test suite and aligning asynchronous API behavior. A targeted bug fix for test stability directly improves CI reliability and the correctness of the clearEventListeners API.
