Worked on the lichess-org/zulip repository to enhance both contributor onboarding and user interface accuracy. Addressed documentation hygiene by correcting a typo in the CONTRIBUTING.md file, clarifying instructions for new contributors and reducing onboarding friction. Improved frontend logic by fixing the user activity status display, ensuring the sidebar accurately reflects real-time user presence by prioritizing active timestamps over idle ones. Utilized JavaScript, TypeScript, and Markdown to implement these changes, focusing on clear commit-level traceability. The work contributed to lowering support overhead and increasing user trust in real-time indicators, demonstrating attention to both technical detail and user experience.
