PROFILE
Andrzej Pietrzak
Over a three-month period, contributed to the NHSDigital/ftrs-directory-of-services repository by building and enhancing a data migration testing suite focused on service data reliability and security. Developed end-to-end and integration tests using Python and behavior-driven development to validate triage-code mappings, opening hours, and service endpoints, ensuring accurate data transformation during migrations. Improved the CI/CD testing framework, refined DynamoDB table handling, and implemented fixes for entity key inference and table name usage. Updated KMS configuration with Terraform to strengthen encryption and access control. These efforts reduced migration risk, improved data integrity, and aligned the workflow with security and compliance requirements.
