PROFILE
Sathiyakumar Ganesan
Over six months, contributed to the NHSDigital/identity-service-jwks repository by engineering secure, scalable API authentication and key management solutions. Developed and maintained JSON Web Key Sets (JWKS) for multiple environments, enabling robust authentication and seamless key rotation across services. Leveraged Python and YAML to automate key provisioning, expiry monitoring, and secure labeling, integrating with CI/CD pipelines and Jira for traceability. Enhanced security posture by implementing public key infrastructure, cryptographic hashing, and vulnerability scanning workflows. Upgraded dependencies and runtime environments to align with evolving standards, ensuring compliance and reliability. The work reduced operational risk and improved cross-service trust through auditable, automated processes.
