Developed and integrated organization-level access control and authentication middleware for the cornellh4i/CHEM repository, focusing on enhancing security and data integrity in a multi-tenant environment. The work involved implementing authorization checks and ownership verification for transaction and contributor endpoints, ensuring users could only access data belonging to their organization. Leveraging JavaScript, TypeScript, and Firebase, the developer enforced UID-based organization resolution and sanitized incoming requests to prevent unauthorized data reassignment. These changes scoped endpoint access to the caller’s organization, reducing the risk of cross-organization data exposure and enabling scalable governance. Collaboration was demonstrated through co-authored commits and comprehensive middleware enhancements.
