During Oct 2025, delivered a Healthcare Authorization Framework: an NGINX-based Policy Enforcement Point (PEP) integrated with a Policy Decision Point (PDP) to enable policy-driven access in healthcare apps. Implemented mock token introspection, OPA-based PDP calls, Docker image builds using nginx:1.29.2-alpine, and a Helm chart for Kubernetes deployment. The work includes environment-driven configuration, health probes, and Gateway API HTTPRoute support for scalable, Kubernetes-native deployments. Fixed key issues such as default FHIR backend port alignment (7050) to prevent conflicts and added a logs volume for easier debugging. Enhanced quality with unit tests for authorization logic and PR-driven refactors to align naming. Delivered end-to-end readiness with CI artifacts (GH Actions) and production-ready templates, enabling centralized access control across services and improved security posture.
