I build full-stack products, backend systems, accessible interfaces, and applied AI features.
My favorite work sits where product ideas meet real engineering: clean APIs, usable interfaces, reliable data flows, thoughtful testing, and practical AI tools that make software more useful. I recently completed my M.S. in Computer Science at Rochester Institute of Technology, with additional degrees in Web & Mobile Computing and Mobile Application Development.
