Everything will be delivered as **clean, maintainable, production-ready code** with proper responsiveness and performance optimization. With **6+ years of frontend development experience**, I’ve worked on similar projects involving API integration, payment systems, and tracking setups.

Hello there, I can help with this project. With 13+ years of experience, I've worked on custom web development involving frontend builds, APIs, payment gateways, and third-party integrations. I focus on clean, reliable development and would be happy to share similar work once we connect. Will the frontend be integrated into an existing system, or is HTML delivery the final requirement? I'd be glad to discuss the project. Thanks, Regards.

Your project aligns well with my experience in frontend development and third-party integrations. I can convert your PSD designs into **pixel-perfect, fully responsive HTML**, integrate REST APIs, implement secure payment gateways, and configure affiliate tracking to ensure accurate conversion reporting while keeping the code clean, optimized, and well-documented. I have hands-on experience with **HTML5, CSS3, JavaScript, REST APIs, Stripe, Razorpay, PayPal, webhooks, Facebook Pixel, Google Tag Manager, and affiliate conversion tracking**. I'm available to start immediately, provide regular progress updates, and thoroughly test all integrations before delivery. One recommendation is to implement **a reusable API and payment service layer** instead of embedding integration logic directly into the UI. This makes future gateway or API changes much easier without affecting the frontend. **One question:** Will the PSD be converted into **static HTML only**, or will it later be integrated into a framework such as **WordPress, React, or Laravel**?

The third‑party affiliate pixel often conflicts with the same domain cookie, so I’d isolate the tracking script in a sandboxed iframe to avoid data loss. I’ll start by converting the PSD into a semantic HTML layout, then layer in the CSS grid for full responsiveness before wiring up the API calls. After the front‑end is solid, I’ll plug the payment gateway using its server‑side SDK and run end‑to‑end tests. A common mistake is hard‑coding API URLs, which breaks when the environment changes; I’ll keep them in a config file and add a simple health check to catch issues early. You’ll get clean, commented code that passes validation and works across browsers, plus a quick handover document for future updates. ready to start immediately
