C#, ASP.NET Core Web API (.NET 10), EF Core, Swagger/OpenAPI, Docker
● Built a solo REST API for conference room booking with dynamic time-based pricing (4 time bands with surcharges/discounts) and
additional-service selection (projector, Wi-Fi, sound).

domain-specific repositories for availability search and overlap detection.

(DTO + service layer); documented all endpoints via Swagger UI.
