Over four months, contributed to earthhistoryviz/tsconline by delivering six features focused on chart configuration, session management, and team transparency. Leveraging TypeScript, Node.js, and React, implemented per-session chart state personalization, robust authentication, and enhanced chart settings with improved column toggling and width options. Strengthened code quality through Yarn-based QA checks, added tests and documentation, and maintained clean commit history via rebasing and conflict resolution. Enhanced the About page to improve onboarding and transparency. The work emphasized reliability, maintainability, and secure access control, with a full stack approach spanning backend development, data visualization, and front end enhancements without reported bug fixes.
