Raynato Pedrajeta enhanced the hyperledger-cacti/cacti repository by addressing a critical security issue in the Fabric Connector, replacing SSH-based authentication with a JWT-based system for the API server. Using bash and typescript, Raynato automated the generation of authentication tokens and keys within the CI/CD pipeline, which improved both security and deployment reliability. This work resolved a DAST scan failure caused by missing SSH configuration, allowing the Fabric Connector to operate without SSH dependencies. By focusing on backend development and DevOps practices, Raynato’s contributions reduced deployment risk and improved the project’s security posture, demonstrating depth in secure, scalable integration workflows.
