Over eight months, Chang Kim engineered robust data visualization and asset management features for the earthhistoryviz/tsconline repository. He developed secure, scalable API endpoints for map image delivery and datapack uploads, applying Node.js and TypeScript to enforce strict path validation, authentication, and rate limiting. Chang refactored chart generation logic to support dynamic geological time scales and external data sources, improving reliability and reducing manual intervention. His work included frontend enhancements in React, internationalization updates, and comprehensive error handling. By integrating thorough testing and code cleanup, Chang ensured maintainable, secure workflows that improved data integrity, admin governance, and user experience throughout the platform.

Jan 1, 2025January 2025 (2025-01) focused on security hardening and robustness for map asset delivery in earthhistoryviz/tsconline. Delivered a Secure Map Image Access and Path Handling feature with a dedicated route to fetch map images from the uploads directory, enhanced access control, increased rate limiting, and path normalization. Refactored path traversal utilities into a shared module and introduced dynamic asset upload directory configuration to improve deploy flexibility and security. These changes reduce exposure to path traversal vulnerabilities, improve reliability under higher load, and facilitate maintainable, scalable asset management across environments.
