I have extensive experience with building online stores, such as the two below which were built in WordPress. I've assisted students in WordPress classrooms who were building online stores and given presentations about online selling in WordPress classrooms as well as local WordPress meetups. I've also built stores in Shopify which is not WordPress but can be linked to WordPress sites or used as a stand alone program.
