Hi, I just read your job posting and it sounds like you want to integrate the payment gateway on your squarespace site. I can perfectly do this for you.
I have been working on WordPress, Laravel, PHP, Flutter, API integration, Node.js and many more technologies for the past 5 years.
I will begin your work immediately and complete it as soon as possible with 100% satisfaction. I have few queries to ask before taking a next step. When is a good time for you to discuss them?
I will wait to hear back from you.
Best regards,
