About

I care about what catches your visitors' eyes, not just what works behind the scenes.

Most developers focus only on the technical side. I focus on what you actually need: something that looks good, feels right to your users, and helps you reach your goals. I've worked with startups and large companies, and the lesson is always the same—the best code means nothing if visitors don't convert.
