Worked on the jaypatelll1/csi-aptitude-portal repository to deliver a feature enabling detailed exam result retrieval, allowing users to see whether each response was correct or incorrect. Focused on backend development using JavaScript, Express.js, and SQL, the work involved refactoring result retrieval functions for improved clarity and robust error handling. Updates were made across the controller, model, and route layers to support the new functionality. This enhancement provided granular analytics capabilities and improved the reliability of result computations, laying the foundation for future dashboards and advanced reporting. No bugs were fixed during this period, with efforts concentrated on feature delivery.
