Knowledge of Magento2, API, PHP, Self Built Application within Magento, Javascript, MYSQL. If you do not have the right skills and are not familiar with Magento your pitch will be ignored. We are nearly finished building our bed designer application which works within Magento (2) see here: [login to view URL] When a customer designs a bed they can mix and match different parts of the bed to build their perfect bed. However some parts are not available in various sizes. At the point where the customer cannot choose a particular part we give them an option to continue designing or to see an alternative bed based on the unavailable option. At the moment this option is given it is not giving the desired bed. We need a clever little bit of programming to give the customer an alternative bed. So the code will need to be edited to get the desired result. We can explain the desired process logically. A more detailed explanation will be explained to the awarded freelancer.
