Summary

As a career Oracle Commerce (ATG) consultant and full-stack web developer, I've designed, built, and optimized commerce web applications for some of the top retailers in the world. Though my focus has been primarily on back-end web technologies (being that Oracle Commerce is a Java/J2EE-based commerce framework), my passion has always been in working with front-end web technologies. I've most recently been helping retailers adopt a mobile-first mindset towards their web development cycles and have been heavily involved in the design and construction of a number of responsive user interfaces for our applications. Going forward, I want to continue to focus on front-end web development and apply my knowledge and expertise to design and build the next generation of highly responsive web applications.
