Worked on the affinidi/affinidi-ssi-dart repository to enhance the maintainability and consistency of security token generation. Focused on an internal refactor, the developer standardized JWS generation by renaming a proprietary method to a more generic one and updated all related call sites, reducing domain-specific coupling and improving code readability. The work included removing affinidi-specific links from the JWS logic, resulting in a cleaner and more maintainable codebase. Utilizing Dart and applying expertise in cryptography, digital signatures, and verifiable credentials, the changes set a foundation for safer future enhancements and streamlined onboarding for developers working with security tokens.
