About Me

I build modern full-stack web applications—everything from dashboard-style internal tools to fun, interactive projects like Downcard. I'm comfortable across the stack: CRUD, APIs, and UI/UX that feels clean and fast. I started in interactive multimedia (game design) at Eastern Kentucky University, then moved into a core computer science degree at Bellarmine University. Lately I've been leaning into AI-assisted development and workflow automation, and I'm interested in going deeper into building real AI-powered tooling—not just using it. I'm also drawn to building more meaningful applications—projects that help people, save time, or genuinely improve someone's day.

Open to opportunities
