Over a three-month period, contributed to the JinOptimist/NET21Online repository by building and enhancing a Coffee Shop web portal with robust product management, user authentication, and real-time features. Leveraging ASP.NET Core, C#, and React with TypeScript, developed backend APIs, implemented database migrations, and integrated localization for multi-language support. Introduced end-to-end testing using Selenium WebDriver and NUnit, improved UI/UX with AJAX-driven interactions, and enabled API endpoint introspection through reflection. The work stabilized user access, streamlined onboarding, and improved data integrity, while the addition of a React frontend and external API integrations enhanced both performance and user engagement across the platform.
