I run https://miamibeauty-salone.biz on Magento 2.x and need a specialist to integrate additional payment gateways so the checkout flow is rock-solid from authorization through refund. What I need you to do • Connect the chosen gateway(s) in both sandbox and live mode, handling API keys, webhooks, and order-status mapping. • Write or adjust a lightweight MiamiBeauty-namespaced module only if core overrides aren’t enough. • Make sure the solution is PCI-DSS compliant, passes Magento’s built-in readiness checks, and leaves no console or server errors. • Document every code change and admin configuration, then commit to a dedicated Git branch so I can review before we merge to production. Acceptance criteria 1. Test orders succeed for authorize, capture, void, and refund. 2. No new critical or major issues appear in Magento’s logs or the browser console. 3. Clear, step-by-step deployment notes are supplied. I’ll provide SSH, Git, and admin access as soon as we start. Let’s get the integration done smoothly and swiftly.
