I am new to freelancer.com but I am an expert in Javascript. I have created app using different JS framework like angularjs, vuejs and reactjs to make it look and feel like an native application. I have also created a POS in the past. I know the challenges in creating that kind of system. Printing barcode label is not that hard. I can create a barcode customizer for you where you can print diff kind of barcode using ean13 type or code128 or other types you prefer. Rest assured that I can deliver the app on time and bug-free. Thanks
