My name is James Royal and I’m a Software Leader, Architect & Engineer with 15+ years of product engineering, development, and architecture experience.

“Average engineers - these engineers would just like to be left alone.

Good engineers - really want to be coached.

Great engineers - Want to be told the truth, and these engineers are always seeking the truth in terms of what they can do — character, attitude, competition, and technical execution; Honing their skills to get better every day. These elite engineers showcase true software craftsmanship in every aspect of their work.”, James Royal
