Worked on the NHSDigital/ftrs-directory-of-services repository, delivering ten features and resolving three bugs over six months. Focused on API development and backend reliability, the work included building health check endpoints, implementing endpoint-level AWS Lambda architecture, and enhancing security with API Gateway rate limiting and a regional WAF. Leveraged Python, Terraform, and AWS services to standardize infrastructure, automate CI/CD pipelines, and improve observability through CloudWatch and structured error handling. Introduced sandbox environments for safer testing and accelerated QA, while strengthening API robustness with request validation and dependency management. The approach emphasized security best practices, scalable serverless design, and operational consistency.
