Welcome to the forum and the indsutry as a whole, In my role as a front end developer I work primarilly with websites, with the whole responsive revolution going around we find our websites scale to all devices, yet while mobile sites are frequently visited they rarely convert, especially in the e-commerce world so I'm experimenting a lot on improving the mobile interfaces on the sites our agency develop - The mobile world throws up a whole new host of obstacles, it is challenging but very rewarding at the same time. My mission is to increase mobile conversion as it is a pretty much untapped potential at the moment.
