Summary Of Experience

For over 15 years I have developed high quality mobile applications, web applications, and APIs. I led teams in the finance, gaming, telecommunications, and consumer products industries.

I build software for two audiences: the customer, and my fellow engineers. I passionately design and implement reusable, extensible, and testable code in the form of deliverable libraries. This lets my team work faster—and safer—allowing us to solve customer problems, not engineering issues.

I love to share my knowledge with others, especially people who are new to my team or to application engineering as a whole. Building a team of cross-discipline experts makes work—and the product—better.
