About

Since 2020, I’ve been designing and building software—from the interface someone actually clicks through, down to the backend logic, the database that stores everything, and the deployment that gets it live. I work as an independent developer, which means I’m the one person across the whole project, not one specialist in a rotating cast.

I start with the problem you’re trying to solve, not a specific technology or framework. My focus stays on what actually moves your business forward, and I stay directly involved from planning through launch and any agreed post-launch support, so you’re always working with the person who built it.
