I can provide help with your Shopify store either on the front-end using theme modifications or additions all the way to making full professional custom Shopify apps. I spent 7 years working for a digital agency that was verified as 'Shopify Experts', which they gained while I was the only developer, so I have years of experience making Shopify apps using my own frameworks in either PHP or Node.JS with Twitter bootstrap for quick easy UI. I can help make inventory syncing apps custom for whatever your supplier/warehouse system uses - if it has any type of API, REST or otherwise - I can make you an app that syncs it all up for you. Please get in touch today and we can discuss taking your Shopify store to the next level.
