PROFILE
Sylwia Luczak
Sylwia Luczak-Jagiela developed and enhanced automated data migration and validation test suites for the NHSDigital/ftrs-directory-of-services repository over a three-month period. She focused on building integration tests that validated phone and email transformation, service migration data integrity, and audit event tracking, ensuring reliable data handling and traceability during migrations. Using Python, AWS DynamoDB, and behavior-driven development practices, Sylwia expanded end-to-end test coverage and improved the resilience of service endpoints. Her work emphasized automation, transactional data validation, and auditability, resulting in maintainable, CI-ready test suites that reduced migration risk and enabled faster feedback cycles without requiring major bug fixes.
