I’m building a WordPress site and need an experienced developer who is equally comfortable inside the WordPress dashboard and in raw PHP. Your main task will be to integrate a reliable payment gateway so that transactions run smoothly and securely, but I may also tap into your skills for theme or plugin tweaks as we go. Here’s what I expect as concrete deliverables: • A fully functional payment gateway integration (Stripe, PayPal or similar – we’ll finalise the choice together) • Clean, well-documented PHP custom code or hooks used in the process • End-to-end testing with test cards and live mode switch-over • A brief hand-off guide showing where key settings live and how to add new products or plans Please be confident with WordPress core functions, custom post types, hooks/actions, and best-practice security. If you have recent examples of payment work, share a link or two so I can see how you approach checkout UX. I’m ready to start as soon as I find the right fit and I’m happy to answer any technical questions you might have before you dive in. Let’s make checkout seamless for our users.

I’ll implement a production-ready payment gateway flow (Stripe/PayPal or your final pick) using WordPress best practices: proper hooks/actions, reliable data handling, and secure callbacks/webhooks. The work will include: custom PHP code (or plugin-style hooks) that maps checkout results to orders/subscriptions, end-to-end testing using test cards plus a smooth switch to live mode, and a brief hand-off guide pinpointing where gateway settings live and how to add new products/plans. I’ll also support any necessary theme/plugin tweaks to keep the checkout UX fast, consistent, and easy for users. Which payment gateway (Stripe, PayPal, or other) do you prefer first, and what order/subscription data model should the integration update in WordPress?

I’ll integrate your payment gateway (Stripe or PayPal, we’ll finalise together) into the WordPress site with clean, documented PHP using proper hooks — no core hacks — then test end-to-end with test cards, switch to live mode, and hand you a short guide on where the settings live and how to add new products or plans. I’m comfortable with custom post types, hooks/actions and security best practice, and can pick up theme/plugin tweaks as we go. Closest proof: Muhamed’s WooCommerce checkout and item-count fix (5.0) — checkout logic debugged and shipped. Two questions: is the store WooCommerce or a custom PHP flow, and are you selling one-off products or recurring subscriptions? Reply and I’ll outline the integration steps and test plan.
