Worked on the rapid7/strimzi-kafka-operator repository to enhance API credential management with a focus on security and maintainability. Refactored backend systems to transition from user-managed to co-managed credentials, ensuring only essential users are included during credential generation. This involved updating the HashLoginServiceApiCredentials logic and removing stale Cruise Control API users, aligning the system with a new security model. Documentation was revised to clearly communicate these changes and support the updated approach. The work leveraged Java and AsciiDoc, applying skills in API management, backend development, and Kubernetes operators to deliver a more robust and streamlined credential handling process.
