Shopify Store Updates & Management & New Store Building

Hi, I have several shopify stores, some are mine, some are my clients.Sometimes I need a brand new store created for a client.I need these stores updated.Sometimes there will be a little work, sometimes, more work.I need someone who can design and actually run and manage a shopify store. You must have 3+ years experience and have built and managed at least 25+ stores.You must be able to understand ALL shopify apps, plus be able to run the entire backend of a store.
