David has a deep hands-on technology background and extensive experience designing robust, scalable systems. Software he has architected at Calavista is currently in production at Nissan, American Express, the Heritage Foundation, and a variety of smaller companies.

He is not tied to any particular technology stack and is therefore able to make recommendations that provide an optimal technology solution aligned with business goals.
