Worked on enhancing reliability and maintainability for the lichess-org/lila codebase, focusing on user-facing gameplay and interface improvements. Addressed four key bugs by refining in-game chat warnings to trigger only in losing positions, fixing stale premove persistence on reconnects, and improving sitting feedback logic for accurate user outcomes. Undertook broad codebase cleanup, consolidating pagination logic into a shared module to reduce duplication and improve maintainability. Applied Scala and TypeScript to strengthen type safety, accessibility, and UI consistency, including keyboard navigation enhancements. The work emphasized functional programming principles and careful module organization to deliver a more robust and accessible user experience.
