Andrey Moiseenko developed a comprehensive Lessons Management System for the JinOptimist/NET19Online repository, delivering end-to-end CRUD functionality, YouTube embedding, and level categorization with PostgreSQL-backed persistence. He implemented secure user authentication and role-based access control, integrating these features into lesson workflows and providing an admin UI for user and permission management. Andrey enhanced moderation by adding banned words detection and user banning, and enabled dynamic user role changes through repository and UI updates. His work, using ASP.NET Core MVC, Entity Framework Core, and Razor, improved security, modularity, and maintainability, resulting in a scalable, well-structured backend and user governance system.
