Andrew Marich

I'm a full-stack engineer out of Gilbert, Arizona. Grew up in Tucson and got my start in Finance at the University of Arizona, realized I liked building software more than analyzing spreadsheets, and went back for a Computer Science degree from WGU.

These days I split my time between two roles. At B1 Marketing Group I'm developing the company's software and tooling from the ground up. I'm also CTO and co-founder of Balance, a medical billing platform.

I'm right at home between the technical and business side of things, and understanding what drives each helps me build better products.

Outside of work I spend most of my time with my wife, our daughter, and two Labs who think they run the house... they're probably right. Big on sushi, hoops, and video games.

Lead intake and routing system for legal services. Call center agents fill out dynamic forms, the system validates and enriches data through third-party APIs, then routes qualified leads to the right vendors. Built with HIPAA compliance baked in.
