    • About

    Combining my background in marketing with my passion for software and technology, I excel at creating solutions tailored to meet the business needs of any company with a marketing focus. Which happens to be most of them. Yay! My designs grab attention, direct decisions, and create a warm, intuitive and, (if I can help it) fun experience for users.

    I am self taught - learning most of what I know today from diving headfirst into projects. At first as a hobby - creating gizmos for my own personal amusement (See Projects) - and then gradually, by creating products that do more than turn my lights on or water my plants. Products that serve real businesses, with real needs.

    When I am not hunched over my computer trying to find that god forsaken bug that has broken my whole application, I am usually creating music, learning a new trade or skill, or taking a hike with definetly not enough water (its never enough).
