Suraj Kumar focused on stabilizing and maintaining authentication and API infrastructure across several govuk-one-login repositories, including ipv-cri-otg-hmrc and ipv-cri-address-api. He addressed operational risk by rolling back experimental features, such as Open Telemetry instrumentation and PII redaction, restoring secure token handling and baseline processing flows. Using Java, TypeScript, and AWS CloudFormation, Suraj reverted changes to IAM roles, JWT signing logic, and API Gateway configurations, ensuring compatibility and reliable secret management. His work emphasized disciplined rollback practices and secure-by-default engineering, resulting in improved reliability, maintainability, and alignment with product expectations for backend authentication and integration services.

July 2025: Stabilized AWS access for govuk-one-login/ipv-cri-otg-hmrc by reverting the Secrets Policy update and restoring the prior IAM role ARN for encrypted resources (KMS and Secrets Manager). This rollback prevents policy drift from impacting secret access and encryption key management, ensuring reliable operation of critical authentication flows and secret retrieval. The change was implemented via the commit that reverts the feature update to the TEAM role policy (d51907540f7adf935f1268eba48e81deb6df8c5b).
