Darius Ionica
Software Engineer | .NET Web & WPF Desktop Applica
Category : Mobile development
I am a dedicated Software Developer specializing in the C# / .NET ecosystem, with proven experience building scalable web applications and robust desktop software. My expertise spans across full-stack development using ASP.NET Core and Angular, as well as engineering custom desktop utilities using WPF and the MVVM architectural pattern.
With a strong foundation in object-oriented programming, RESTful API design, and database architecture, I have successfully delivered complex projects—from comprehensive property booking platforms with secure role-based access to specialized medical imaging management systems.
My core technical stack includes:
- Backend: C#, ASP.NET Core (Web API & MVC), Entity Framework Core
- Frontend: Angular, HTML, CSS, Bootstrap
- Desktop: WPF, MVVM Architecture
- Databases: SQL Server, Code-First Migrations
- Concepts & Tools: REST APIs, JWT Authentication, Identity, Git, Azure, Agile/Scrum
I pride myself on writing clean, maintainable code and implementing robust separation of concerns (like the Repository pattern). Whether you need a secure backend built from scratch, a dynamic single-page application, or a tailored Windows desktop application, I am committed to delivering high-quality, efficient solutions that meet your business needs.
