PROFILE
Yannick Rudolf
Yannick Rudolf developed the math-mate platform in the TDT4290-Gr6/math-mate repository, establishing a modular, domain-driven backend with robust authentication and data modeling. Over two months, he implemented core features such as country management, user authentication, and solve tracking, using TypeScript, Next.js, and Prisma ORM. His approach emphasized dependency injection, repository patterns, and schema validation to ensure maintainability and scalability. By integrating NextAuth and Supabase for secure authentication and refining data access with Prisma, Yannick enabled rapid feature delivery and reliable testing. His work addressed both architectural foundations and practical workflows, resulting in a well-structured, testable codebase.

Oct 1, 2025October 2025 focused on strengthening the product’s foundation: authentication, data modeling, and data access patterns to reduce risk, improve security, and enable scalable growth. The team delivered core capabilities and architectural improvements that directly support faster feature delivery and a better developer experience. Key features delivered: - Entities Data Modeling Improvements: defined entity models aligned with Supabase; refined via coderabbit’s suggestions to improve data integrity and migration readiness. - Authentication and Authorization Infrastructure: established a robust auth flow with Supabase and middleware, implemented signIn/signOut in the authentication service, wired authService into DI, and adopted NextAuth as the primary authentication mechanism. - Prisma-based Data Access Layer: introduced Prisma-based data access with a singleton Prisma client and DI wiring for user and country repositories, improving data access patterns and performance. - User Authentication System: implemented sign-in controller, use case, and repository interface; integrated NextAuth including a signIn page. - DI-driven, Modular Architecture: expanded DI graph for sign-in, get countries, set country, and solves flows; introduced mock repositories to enable testing and faster iterations while keeping production parity. Major bugs fixed: - Fix(repository): convert createCountry id from string to int and synchronize with database. - Fix(next-auth): update signIn to be more generic and robust. - Mock/Auth cleanup: apply latest changes to mock auth and remove unused Supabase auth files. - Middleware improvements: add matcher to avoid protecting static assets. - CreateCountry validation: remove parameter from validateSession to fix the validation flow. - Sign-in and DI fixes: adjust signIn controller/use-case wiring; fix DI to return usersModule and update environment variable handling where needed. Overall impact and accomplishments: - Strengthened security posture with NextAuth, reduced production risk through consistent DI wiring, and improved data integrity via Prisma integration. - Enabled scalable multi-provider authentication readiness and streamlined onboarding for new developers. - Established modular, testable architecture for countries, solves, and user flows, accelerating future feature delivery and maintenance. Technologies and skills demonstrated: - NextAuth, Supabase authentication, and middleware patterns - Prisma ORM: schema setup, singleton client, repository integration - Dependency Injection and modular architecture - Repository pattern, mocks, and test scaffolding - Server actions (experimental) and related orchestration concepts - Documentation and developer experience improvements

Sep 1, 2025September 2025 (2025-09) milestone: established a scalable foundation for the math-mate project with a structured architecture, enabling rapid feature delivery and robust testing. Delivered a complete bootstrap of the project, domain-driven design elements for country management, authentication scaffolding, and DI wiring. Implemented the core country domain end-to-end with entity, repository interface, and create-country use case, plus infrastructure mocks and interface adapters. Fixed path alias issues and improved type safety, preparing the codebase for reliable growth.
