Changes in Prestashop checkout page

We need a skilled developer that can help with various changes in a PrestaShop checkout page. You have to make some lookups using the customer's phone number - there are API for this. Besides this, you need to make the styling of the existing checkout page. We only want to get in touch with developers who are skilled and can document other tasks in order to show that they can handle the task. When you respond, then finish your answer with the result of 2 + 2 - thus I can see that you've read our description. If there is no result, we will not consider you. Are you a skilled developer, then there will also be other tasks. Besides the above, you could communicate with us in Denmark within our working hours that are 8:30 to 17:00. Bid ONLY if you are skilled and can deliver and is stable and good English. Jens
