Developer · Commerce · Systems

I build digital products end to end.

I build websites, apps, and commerce systems that help businesses actually run and grow. That includes full stack development, Shopify and e-commerce, POS systems, online marketplaces, digital ads, analytics, and the custom tools that connect it all.

Built across disciplines.

I’ve worked across software, science, data, commerce, and leadership. Different problems, same approach: figure out how the system works, find what can be better, and build it.

HAVE AN IDEA?

Let's build
