Generator Product Mockup online

We´re looking for a developer who can create an API to integrate our website: [login to view URL] What we are looking for is a Generator Product Mockup online from a JPG image that users load. We sell customized products such as wall frame art, posters, canvases, etc. Artists upload designs and automatically present them as mockups simulating the finished product. We want to implement new products gradually (mugs, cases, bags, cushions, etc.) and we think the best to have it in an external API that we can consume. The development is done in JAVA but the API can be done in any language. At the time of generating the mockup, it will be online and expel users. It must contemplate a module of EDITION in LIVE, where the user can move the place, to enlarge, to accommodate its design and that reflected in the model. Here's a clear example of what we're looking to develop: [login to view URL] First we want to start with a particular product, but development should contemplate easily adding new products.

Any concerns can write to us. Thank you very much!
