A little context.

My path to software started in healthcare. Solving practical problems has been the through line.

Today, I’m based in Evansville, Indiana, building products across web and mobile. As a founder, I work directly with customers and take projects from the first conversation through launch and ongoing support.

I value clear communication, teamwork, and close collaboration. Leading projects means managing time, learning quickly, and keeping the customer’s needs in view.
