Worked on the lichess-org/lila repository, delivering seven features and one bug fix over four months focused on accessibility, UI/UX, and maintainability. Enhanced the NVUI by integrating learning tools, implementing perspective-aware rendering, and adding low-time sound notifications that respect user preferences. Improved accessibility through deterministic, locale-based screen reader ordering and ARIA refinements, while streamlining CSS and removing redundant UI logic. Used JavaScript, TypeScript, and SCSS to ensure consistent, maintainable front-end code. Addressed user confusion by removing inaccurate WYSIWYG editor previews, resulting in a more intuitive experience. Prioritized code quality, accessibility standards, and maintainability throughout all development efforts.

May 1, 2026May 2026 monthly development summary for lichess.org/lila: Delivered perspective-aware NVUI updates and UI rendering cleanup to improve cross-perspective usability and maintainability. Implemented color-perspective handling in NVUI commands, aligned piece rendering order with the player's side (including black), extended black-perspective coverage, and removed redundant UI sound logic to streamline behavior. These changes reduce UI inconsistencies, enhance accessibility for players on both sides, and lower future maintenance costs.

Apr 1, 2026April 2026 (2026-04) monthly summary for lichess-org/lila: Key features delivered: - Low time NVUI sound notification: added a time-based sound cue for low-time situations in NVUI (commits e3a16e6d208a930594ac0b48dda149abcdf092e2; 6764c359fe23334a3c50183cef0978622483899e). - NVUI sound notifications respect clock sound setting: NVUI audio now respects the user's clock sound preference and only plays when enabled (commits 9471ca458e1ea50b354e9e5438dea7af9710bcd5; da723596a3a4930451df9dcad522f8acc1734120). - Deterministic screen reader ordering for pieces: deterministic, locale-based sorting for screen reader output to improve accessibility, replacing Map iteration order with a sort via localeCompare (commit a948b5b52e7f7a2dcd01fa66231b354c6067b9cf). Major bugs fixed: - No explicit major bugs fixed documented for lichess-org/lila this month; the work focused on feature delivery and accessibility improvements. Overall impact and accomplishments: - Improved user experience for time management and accessibility, with better alignment to user preferences and assistive technologies. Enhanced consistency of screen reader output through deterministic, locale-aware sorting. Technologies/skills demonstrated: - JavaScript/TypeScript UI logic, NVUI integration, accessibility best practices, locale-aware sorting with localeCompare, deterministic output strategies, and change traceability via commit histories.
