Harihsudhan Kannan modernized the backend of the YSTEMandChess/react repository by migrating the Stockfish server to Express.js, introducing rate limiting, and standardizing ports to enhance stability and scalability. He prepared the codebase for a responsive UI rollout by cleaning up local files and optimizing the local setup to streamline onboarding and pull request reviews. In the following month, he implemented backend support for user streak tracking, designing a new API endpoint and updating the time tracking model using Node.js and Mongoose. His work provided a scalable foundation for gamification features and improved engagement analytics, demonstrating depth in backend API development.
