I'm a .NET developer with around three years of experience building web and cross-platform solutions within the Microsoft ecosystem. I specialize in ASP.NET Core for backend development, Blazor and React for frontend, relational databases (SQL Server, MySQL), and deployments on Azure. I apply Clean Architecture, MVC, MVVM and Vertical Slice principles to deliver maintainable, scalable software: production-ready APIs, modern frontends connected to reliable backends, and cloud infrastructure that holds up under real use.
- Creator of Lume, a .NET MAUI movie recommendation app powered by ML.NET, an ASP.NET Core REST API and MySQL.

- Portfolio of 10+ projects spanning end-to-end delivery, from architecture decisions to deployment.
