Worked on the indigo-iam/iam repository to deliver secure token validation enhancements focused on improving both security and operational efficiency. Developed proxied token introspection and introduced customizable TTL caching for OIDC discovery documents, reducing redundant network calls and minimizing latency. Migrated the caching backend to Caffeine for better performance and memory management, and transitioned deployment workflows to Docker, incorporating docker-compose for streamlined testing and deployment. Leveraged Java, YAML, and Shell scripting alongside skills in Docker, OAuth2, and Spring to align the identity service with business goals of resilience, scalability, and faster go-to-market, demonstrating depth in back end development and deployment automation.
