Worked on the alliance-genome/agr_ui repository to enhance routing stability and support multi-tenant testing environments. Addressed a critical issue by updating BlueGenes URL routing, ensuring all requests were directed to the dedicated multi-tenant TEST environment. This fix improved the accuracy of quality assurance processes by isolating tenant-specific traffic and reducing cross-tenant routing errors. The solution was implemented using TypeScript and AWS CDK, reflecting a full stack approach to infrastructure and application logic. By aligning infrastructure URLs with the multi-tenant routing policy, the work laid the foundation for scalable, tenant-aware testing and more reliable test environments moving forward.
