Worked on standardizing environment-aware deployment routing across DEFRA EPR services by introducing an envToDeploy parameter into the common deployment template, affecting repositories such as epr-common-data-api and epr-payment-service. Leveraged Azure DevOps, YAML scripting, and C# to enable production-like environments to route deployments to SSV5 agent pools while non-production environments use SSV3, improving deployment accuracy and reducing manual intervention. Ensured backward compatibility to prevent disruptions during rollout and unified template changes across 18 repositories, including epr-calculator-api and epr-frontend-accounts. This approach enhanced maintainability, streamlined onboarding for new teams, and increased the reliability and efficiency of CI/CD pipelines.
