Software Engineer · Buffalo, NY

I build payment infrastructure and the full-stack platforms around it — systems that quietly move millions of dollars every week.

Today I'm at Valmar Holdings, shipping serverless payment rails in Go, React, C#, and AWS. Before that, full-stack applications for local-union and small-business clients across Western New York.
