Worked on the hyperledger-cacti/cacti repository to enhance security and reliability by implementing JWT-based authentication for the API server, replacing the previous SSH-based approach. Addressed a DAST scan failure by enabling the Fabric Connector to operate without SSH configuration, thereby reducing deployment risks and improving workflow stability. Updated the CI/CD pipeline to automate the generation of authentication tokens and keys, streamlining integration and reducing manual intervention. Utilized backend development skills with bash, typescript, and yaml to deliver these improvements, focusing on DevOps and security best practices. The work resulted in a more secure, scalable foundation for future Fabric integration.
