I’m a .NET Developer focused on building scalable, reliable applications with C#, .NET 10, ASP.NET Core, MVC, Web APIs, and SQL Server. I prioritize clean, maintainable codebases and apply Clean Architecture, Dependency Injection, Repository Pattern, and DDD fundamentals to keep systems well-structured and easy to evolve over time.

My portfolio includes ASP.NET Core MVC and Web API projects with real-world backend patterns such as authentication, authorization, relational data modeling, API integration, structured error handling, and layered application design.

I also work with modern deployment-oriented development workflows, including Azure Cloud App Service, GitHub Actions CI/CD, Docker, Docker Compose, and containerized SQL Server environments. These additions demonstrate practical understanding of how .NET applications are built, configured, containerized, and deployed beyond a local development environment.

Before transitioning into software engineering, I led international IT and digital transformation initiatives across Europe. That experience strengthened my ability to translate operational requirements into practical technical solutions and collaborate effectively in cross-functional environments.
