Stripe and PayPal Integration for React/Node.js E-commerce Platform

Category: Web Development

Budget: 1150–1150 USDC

We are seeking an experienced Full Stack Developer to integrate a robust payment processing system into our existing custom-built e-commerce platform. The project requires the implementation of Stripe (for credit card processing and Apple/Google Pay) and PayPal Checkout. Key requirements include building a secure server-side checkout flow, handling webhooks for order status updates, and implementing a customer billing portal for subscription management. Deliverables include a fully functional checkout page, automated email receipt triggers via SendGrid, and comprehensive documentation of the API endpoints created. The ideal candidate has extensive experience with Stripe Elements and secure data handling (PCI compliance basics). We expect this project to be completed within three weeks, including a one-week testing phase on the sandbox environment before moving to production. Code must be clean, commented, and pushed to our GitHub repository.
