Worked on security hardening and code quality improvements for the guardian/support-frontend and guardian/manage-frontend repositories. Focused on updating Elastic Load Balancer and frontend listener configurations to enforce TLS 1.3 cipher suites, aligning with PCI compliance and improving Tenable and Nessus pass rates. Enhanced the frontend codebase using AWS CDK and TypeScript, introducing formatting and build-time optimizations such as Prettify and import type-only usage. Hardened ELB policies in manage-frontend to meet strict security requirements, reducing risk and supporting compliance readiness. All changes were thoroughly tested, resulting in faster, more maintainable deployments and a clearer commit trail across both repositories.
