With my diverse skill set and in-depth understanding of ecommerce platforms like Shopify, I am more than ready to create a seamless payment gateway for your website. My proficiency in Node.js enables me to build robust and scalable APIs, which is essential for transmitting sensitive card information securely as you mentioned. On the front-end, I will ensure the billing process is intuitive and user-friendly.
Moreover, as an All-round developer with experience using MERN and LAMP stacks, I can provide your full-stack needs from authenticating the transaction via APIs, storing transaction details in your local servers and sharing API documentation with you such that you can host it on your own servers without any difficulties. My familiarity with both PHP and Node.js further strengthens my position as your potential developer, allowing me to effectively tackle the specific task at hand.
Lastly, I understand the significance of post-development support like deploying and hosting a project. Therefore, I assure you of end-to-end assistance in publishing your app on your chosen server after providing you the source code. It would be an honor to apply my expertise and offer value to your project, turning it into a reality that satisfies even the most demanding user's needs.
