About

I got into software long before I wrote my first line of code — fascinated by how apps work, how websites come alive, and how a few lines of logic can solve real problems for real people. That curiosity turned into a passion for building software that is fast, reliable, and genuinely useful.

Growing up left-handed taught me to notice who software forgets.

Today, I build web applications with a focus on clean code, solid architecture, and great user experience. I enjoy working through ambiguity, breaking complex problems into simple systems, and shipping products that work well without sacrificing depth. I incorporate AI into my workflow where it adds value, primarily as a tool for exploration, debugging, and faster iteration. My focus remains on writing maintainable code, thinking in systems, and delivering software that is both useful and well-crafted.
