Md Hasan Rahman delivered two features across the hmpps-remand-and-sentencing and hmpps-remand-and-sentencing-api repositories, focusing on safe feature rollout and backend data model improvements. He implemented a feature toggle for the court case task list’s save draft functionality, using TypeScript and Nunjucks to ensure UI elements and explanatory text responded dynamically to the toggle state. On the backend, he used Kotlin and SQL to remove obsolete columns and standardize outcome categorization, simplifying the data schema and improving reporting consistency. His work emphasized maintainability and risk reduction, coordinating frontend and backend changes to support controlled releases and clearer feature boundaries.
