Swapnil Patil developed and enhanced backend services for the NHSDigital/dtos-cohort-manager repository, focusing on robust cohort management, eligibility workflows, and secure integrations. Over seven months, Swapnil delivered features such as ServiceNow messaging, NEMS unsubscribe automation, and participant data services, using C#, Azure Functions, and Docker. The work emphasized reliability through comprehensive unit testing, error handling, and infrastructure as code with Terraform and YAML. Swapnil’s approach included refactoring for maintainability, implementing CI/CD pipelines, and strengthening security with measures like regex timeouts. These contributions improved data integrity, automated business processes, and established scalable, testable foundations for ongoing development and deployment.
