About me

I'm a Software Engineer specializing in building scalable, efficient, user-friendly mobile, web, and desktop applications.

I believe that software should be elegant, intuitive, and empowering. My expertise spans across cross-platform development, desktop applications, applied AI/ML, and clean architecture design.
