Note: I have read your requirements and found that you want Coin payment processor.
Good day,
I'm a senior developer with more than 9 years of experience. I have developed many websites which include websites of multinational companies.
I developed websites on WordPress, angular, php, Shopify, Open-cart, Ruby on Rails and Magneto using different variations like Payment method, product type, simple product virtual product, downloadable products and much more.
As a web developer focused on customer satisfaction, I manage all aspects of web development from concept to requirements definition, design, development, launch, maintenance and user support.
I can show you my portfolio if you're interested.
Message me so we can proceed further.
Many Thanks
AQ.
