Jake Reid developed a new onboarding feature for the hmrc/ngr-login-register-frontend repository, focusing on a flexible Unique Tax Reference (UTR) options form. He designed and implemented the frontend form and corresponding Scala data model, allowing users to provide a UTR, a National Insurance Number, or defer UTR entry. His approach included robust data handling through enum formatting and JSON serialization, ensuring reliable data capture and future extensibility. Jake expanded test coverage with targeted unit tests, emphasizing code quality and maintainability. His work leveraged Scala, Play Framework, and frontend development skills to support scalable onboarding flows without introducing new bugs.
