I have integrated Stripe across multiple production platforms including CardsIQ where I handled Stripe, PayPal and Venmo together, and PocketClass where 1,500 active users process payments daily. You get Stripe checkout and payment intent setup, one time and subscription payment flows, webhook handling with signature verification, customer portal for subscription management, success and cancel page handling, refund and invoice management, secure environment variable setup, and full source code delivery. No tutorial level work, just clean production ready Stripe integration that handles real money reliably.
