Dominik Tworek delivered robust identity verification and API infrastructure across the govuk-one-login/ipv-core-back and ipv-core-front repositories, focusing on secure, maintainable backend and frontend flows. He migrated Java-based Lambdas to TypeScript, standardized API gateway configurations, and enhanced JWT handling for improved token validity. Dominik implemented AppConfig pipelines using AWS CloudFormation and YAML, streamlined CI/CD workflows, and strengthened audit logging for compliance. His work included refactoring test automation, improving localization, and optimizing deployment reliability. By integrating technologies such as Java, TypeScript, and AWS Lambda, Dominik ensured scalable, observable systems that reduced operational risk and enabled faster, safer releases for the platform.

February 2026: Delivered a major migration of the API gateway in govuk-one-login/ipv-stubs from Java-based Lambdas to TypeScript Lambdas, including restructuring event triggers, removing Java dependencies, standardizing lambda configuration, and consolidating resources. Introduced CIMIT_PARAM_BASE_PATH across all Lambdas to unify base path configuration and improve deployment consistency. Implemented JWT expiration improvements by using current time in seconds for the exp payload, reducing token drift. Fixed asynchronous loop handling to ensure all async operations are awaited and properly logged, eliminating race conditions. Standardized issuanceDate formatting to ISO date strings (YYYY-MM-DDTHH:MM:SSZ) across affected files for data consistency and downstream processing. These changes reduce runtime dependencies, improve reliability, token validity, and data integrity, and streamline CI/CD, with clearer ownership and easier maintenance.
