Worked on the istio/istio repository to deliver two backend features focused on security and observability for Istio deployments. Developed TLS Inspector support for Waypoint, enabling SNI-based authorization policies and ensuring the inspector activates only on TLS ports, with comprehensive unit testing to validate functionality. Enhanced the istioctl proxy-config secret command by adding trust bundles display, improving output to show trust domain information and refactoring secret parsing logic for maintainability. Leveraged Go for backend development, networking, and security, with a strong emphasis on testing and code quality. The work improved both the security posture and operational visibility of Istio environments.
