Projects

Open-source products, WordPress plugins, and small tools I’ve built over the years.

I’ve been building and shipping software for well over a decade. Some of these projects became businesses, some became widely used open-source tools, and some were mostly an excuse to learn something new.

Mailchimp for WordPress

A WordPress plugin that tightly integrates a site with Mailchimp. It grew from a small open-source project into a widely used product with a paid version.
