John McGuinness

Technology Director / Executive Director

John is a C#/Swift/Java developer with 18 years programming experience with both front-end (web, mobile) and back-end development. 7 years ago, he founded Xerratus and has worked on such brands as Intel, Ford, and Expedia. One of his greatest strengths is saying yes when other developers say no. For him, there is always a solution, a way to accomplish a task. “No” to him is a challenge, a puzzle to solve.
