Mikkel worked on the ErasmusEgalitarian/educado-backend repository, delivering a Student Course Enrollment Management feature using Strapi and TypeScript. He focused on enabling student self-enrollment workflows, implementing validation logic to prevent invalid enrollments and runtime checks to handle duplicate entries. This backend development effort improved user experience by allowing students to manage their own course enrollments while reducing administrative overhead. The work emphasized data integrity and clear commit traceability, ensuring maintainability and transparency in the codebase. Over the course of the month, Mikkel applied his skills in API development and backend systems to address enrollment management challenges in a focused release.
