I understand your constraint: app is built, you need Stripe payment integration + stability before launch. No refactoring, just clean execution. I've stabilised 3 booking platforms (holiday rental, activity booking, charter boat) right before launch. All went from incomplete payments to live with Stripe webhooks, deposit logic, and booking integrity checks. Last one launched in 9 days—zero payment issues post-launch. Here's what I'll do: Implement Stripe payment intents (deposit + full payment flow), webhook handlers to confirm payments and update booking status, duplicate prevention logic with real-time availability validation, error handling with retry paths (no dead ends), and a simple checkout page connecting your frontend to payments. WhatsApp notifications via Twilio is straightforward add-on. I'll work within your existing NestJS + PostgreSQL codebase—no unnecessary rebuilds. Clean, stable, launchable. I'll review your booking flow and confirm Stripe approach. Let's connect! Regards, Ruchita

Getting your yacht booking app ready for launch but hitting roadblocks with Stripe integration and booking flow is incredibly stressful, especially knowing any payment glitch or duplicate booking could cost you real revenue and trust at this stage. With a streamlined Stripe integration, solid booking checks, and a user-friendly checkout, you’ll be able to accept payments with confidence and keep your bookings accurate from day one. First, I’ll connect Stripe for both deposits and full payments, handling all webhooks and payment confirmations. Then, I’ll harden your booking logic to block duplicates and make sure availability checks are airtight. Finally, I’ll link the frontend booking and payment flow so your users get a smooth, reliable checkout every time. Is there a preferred order in which you’d like to address these key areas, or should I start with the payment integration?

Hello, I came across your project and it looks like you're very close to launch, which is great. The key things here are getting the Stripe payments working properly, making sure bookings are accurate, and ensuring the checkout flow is smooth and reliable for users. From what you described, the most important part is handling payments correctly using Stripe (payment intents, deposits vs full payments, and webhooks), and making sure bookings are not duplicated by validating availability in real time before confirming anything. I have solid experience working with Node.js, NestJS, PostgreSQL, and Stripe integrations, especially with webhooks and payment flows. I’m comfortable jumping into an existing codebase, understanding it quickly, and improving it without overcomplicating things. Here’s how I would approach it: Set up Stripe payment flow with deposit and full payment support Implement secure webhook handling to confirm payments and update booking status Add checks to prevent double bookings and ensure real-time availability Connect your current frontend booking flow to a simple checkout experience Handle failed payments properly with clear retry options so users don’t get stuck I focus on clean and practical solutions, and I can deliver this within your 1–2 week timeline. Happy to discuss further and start right away. Thank you.

Hi, Since your platform is already built, the main risk here is not Stripe integration itself but ensuring payment flow, booking logic, and system state remain consistent under real usage. Most issues happen with webhook handling and duplicate bookings. I’ve worked on backend systems where transaction flow and real-time validation were critical, including API-driven systems handling state consistency and event-based updates . I would approach this by integrating Stripe with a strong webhook layer, ensuring idempotency and reliable booking status updates. For booking integrity, I’ll implement backend validation and locking to prevent race conditions before payment confirmation. The checkout flow will support deposit and full payments while keeping the user journey simple. Error handling will include retry-safe mechanisms so users never get stuck in incomplete states. I’ll work within your existing codebase, focusing only on stabilizing and completing the required modules without unnecessary refactoring. If helpful, I can outline the webhook and booking validation approach before starting. Best regards, Amit
