I craft robust, beautiful software at sprint speed.

CS student at Penn State and Apple Pay intern. As a software engineer, I ship production-ready products at sprint speed. After delivering 60+ freelance projects to happy customers, I'm now building Solopreneur, an escrow and workflow platform for devs like me. I move fast, iterate aggressively, and obsess over robust, intuitive interfaces.

By far the easiest and straight forward person to work with. Matt was clear, concise, and understood everything I had asked of him to end up building an exceptional product.
One of the smoothest and most professional experiences I've ever had. Delivered exactly what I had in mind, with excellent communication.
His skill, ability and candor at his age, speaks volumes to who he is not only as a developer but as a person. Great developer all around.
One of the most professional people I have met. Very organised all round! Had the pleasure of working with him as well!
Matt was able to not only meet every request but also communicate to me the intrinsic qualities the project required, and ensured that the final product was perfect.
