Oct 1, 2025October 2025 — JinOptimist/NET21Online: Delivered the Rental Car Management System (Backend API + SPA) and enhanced Tourism end-to-end testing. Implemented a backend API with a database context, models, and service layer, integrated into the shop view for rental car display and CRUD-like operations. Built a React/TypeScript SPA to list cars and add new ones, connected to the API. Strengthened quality with end-to-end testing enhancements for Tourism: added tests for create/delete shop items and stabilized test runs by fixing WebDriver teardown (Close -> Quit) and improving image handling (minsk.jpg). Result: improved inventory management capabilities, more reliable test coverage, and faster feature delivery. Demonstrated proficiency in API design, frontend integration, and automated testing, across the JinOptimist/NET21Online repository.
