I build Shopify apps, ship thoughtful ecommerce products, and partner with founders who care about the details. Based in Manchester, MO — working with clients everywhere.
Both apps hold Shopify's “Built for Shopify” status — their highest bar for performance, design, and integration. I design, build, and support them on my own.

A small selection of what merchants have written on the Shopify App Store.
“Excellent collection of highly customizable sections and blocks. The developer is also highly skilled and responsive.”
“It's elegantly simple which I appreciate — nothing added that doesn't need to be there. I tried other apps and solutions; this is the best.”
“From day one, Matt has been flexible, patient, and incredibly thorough. At no point did I feel rushed or dismissed. It's a partnership.”

I'm Matt — an independent engineer and designer based in Manchester, Missouri. I've spent most of my career in the space where good design meets real code, with a particular soft spot for Shopify and the merchants who live on it.
Today I split my time between two things: running my own Shopify apps — Fundlet and Section Star — and working as a long-term partner for a small number of brands I believe in. I'd rather do a few things really well than a lot of things just okay.
If we work together you'll get one person, fast replies, and the same care I put into my own products.
