02 / Profile

A practical engineer with a product lens.

My background spans mobile applications, web products, and business software. I enjoy turning dense requirements into interfaces and systems that feel direct, useful, and maintainable.

I work comfortably across the stack, with deep roots in C# and .NET and an ongoing curiosity for the right tool—whether that is MAUI, React, Flutter, Python, or native SwiftUI.
