- • ASP.NET, Blazor, DevExpress, and DevExtreme
- • Front-end interfaces with modern JavaScript and UI work
- • APIs, database access, and maintainable architecture
What I bring
I enjoy turning legacy tools into reliable modern applications, whether that means UI development, backend logic, data access, migration planning, or close collaboration with end users.
