PROFILE
Sindhu Natarajan
Sindhupriya Nallamothu contributed to the NHSDigital/ftrs-directory-of-services repository by designing and developing robust API solutions, including the Directory of Services Ingestion API and its supporting infrastructure. She established OpenAPI specifications to define clear contracts, implemented secure custom domain endpoints with mTLS using Terraform and AWS, and enhanced integration workflows through environment-specific configuration. Her work included refactoring ETL services for code quality, aligning API documentation with implementation, and enabling isolated sandbox environments with Docker and FastAPI. These efforts improved onboarding, security, and maintainability, demonstrating a thoughtful approach to backend development and infrastructure as code over a focused five-month period.

Jul 1, 2025Month: 2025-07 — This period delivered security hardening and API readiness improvements for NHSDigital/ftrs-directory-of-services, enabling secure custom domains and streamlined access for future integrations. Implemented Secure Custom Domain Endpoints with ACM TLS certificates for custom domain endpoints, enabled DNS validation and mTLS support in non-management environments to minimize risk. Enabled API Gateway default execute endpoint and standardized the Organisation endpoint naming across services/docs, removing the IAM authorizer to simplify access. Prepared the platform for upcoming APIM, ETL, and Dos Reader integrations with improved consistency and governance.
