Currently we have a wordpress website, but we are integrating everything to Magento 2.3. We want this to be a headless website with a custom front end connected to the magento back-end. We have the designs (front end) ready and want our custom front end to be connected with the back end through API.
We also have th POS system (megastore) with our inventory system, crm, loyalty system and other extentions. Because we are using other (customized) systems currently we want some extentions to be custumized to our needs. We also want to create fullfilment rules to automize some processes.
