please gojs, php , mysql!!!!!

I'm looking for a developer who is good with javascript, we are looking to build a module for our software and will need to integrate GoJS with PHP, particularly, the process will be 1) user build the flow using GoJS to draw the diagram 2) Once it's done, user will click save, the script will create a record in the DB using PHP for each step / box of the diagram. 3) We will need you to build the module using our bootstrap and prefer to have everything done using composer. We will upgrade this system later to make it more advance but this is it for now. Thank you.
