About this gig

Today, payment security is a matter of trust between you and your customers, from the moment your customer initiates a payment, every step is routed through a PCI DSS compliant transaction flow I design from the ground up, combining the flexibility of a custom payment gateway integration with the strength of trusted payment processors like Stripe and co.


Whether you need to accept one time payments, or automate subscription workflows, I develop a robust processing engine that fits seamlessly into your existing infrastructure or acts as a standalone merchant processing layer. The system includes built in fraud detection mechanisms, multicurrency support for global audiences, and a clean RESTful API that simplifies future integrations.


My process kicks off with a deep dive into your requirements, where I map out the optimal processor and settlement flow for your niche. Then I move into development and sandbox testing, ensuring every scenario from successful charges to declined transactions is handled gracefully. The security of your customer data is nonnegotiable, all sensitive information is tokenized and routed according to strict compliance.
