I am Luis Diego Campos, a Software Engineering student at Universidad Técnica Nacional. I build web and desktop applications with a focus on business rules, architecture and software testing.
Backend & desktop · C# / .NET / ASP.NET Core / Windows Forms
Frontend · React / JavaScript / HTML / CSS
Data & quality · SQL Server / EF Core / ADO.NET / xUnit
Web development · Software testing · Team collaboration
A laboratory reservation system developed for UTN's Software Testing course. Combines a React interface with an ASP.NET Core API and SQL Server.
- Reservation validation: dates, operating hours, maximum duration and overlapping bookings.
- Authentication with user roles and failed login controls.
- Unit testing and documented test cases.

What to look for in this project
Follow the flow from a reservation form to backend validation and database persistence. The README documents business rules, test scenarios and local setup.
This is an academic project under continued development. Run it locally using the repository instructions.
Desktop development · Layered architecture · Data management
A condominium management desktop application covering properties, residents, billing, payments, common-area reservations and reporting.
- Built with WinForms, .NET Framework 4.8, ADO.NET and SQL Server.
- Separates presentation, business logic and data access.
