I love Mobile App Development & Front End Programming. I am an expert in developing Hybrid Apps with HTML5/CSS/JS/PhoneGap on the Front End and PHP/MySQL on the backend. I create amazing mobile App's by following principled standards to deliver predictable results through steadfast action. Beyond engineering, I help clients with their overall product strategy, architecture, and product development.

In my free time I just launched a 4-video teaching program where I teach non-programmers how to turn their idea into a published App in iTunes & Google Play. It's the entire process from idea, to planning, to hiring developers, to testing, launch, marketing and ASO (app store optimization).
