Freelance Full Stack Developer

I build fast, custom websites for small businesses.

Your site should look like it belongs to your business, not a template, with design and details that feel professional and code underneath that's fast, secure, and built to hold up. Based in South FL, CS grad from the University of Florida.

About me

I'm a freelance full stack developer who works with small businesses in South Florida to build websites made specifically for them. I hold a Computer Science degree from the University of Florida and have spent the time since working directly with clients on real projects.

My core stack is React, Next.js, Python, and TypeScript, though I'm also comfortable working closer to the metal when a project calls for it, including building an HTTP server in C from scratch. If your business needs a website built well and built to last, feel free to reach out!.
