Joseph Petty

Owner, Lead Developer

Former US Naval Nuclear Reactor Operator, and Control Room Operator for a National Laboratory. After years of side work as a developer, I switched careers and started my own company to help other businesses go paperless.

I also have a background in engineering, construction, and manufacturing, and I enjoy building apps for related fields. My hobbies include mountain biking, running, playing guitar and brewing beer. 


  • Adrea with MSU

    "Joseph is communicative, so easy to work with, and could anticipate exactly what I needed. He created a computer application with a database for my team at Michigan State University that we can use for several research studies. He was incredibly flexible with my changing needs and offered great ideas throughout development, beta testing, and user testing. I will be coming back!"
