About Me

Architecture

I'm a software engineer who enjoys working across different layers of technology. My experience spans modern, responsive interfaces for web and mobile (React, Next.js, React Native) all the way to native desktop applications and system extensions for Linux/GNOME built with Python and JavaScript.

I believe in using technology to solve real-world problems simply and efficiently. I combine technical rigor, sound design principles, and smart automation in my daily workflow to build experiences that are robust under the hood and seamless for the user.
