I will integrate stripe, paystack payments and secure webhooks in your backend

When you are dealing with real money, "close enough" code is an operational liability. A poorly built payment gate system results in dropped orders, double charges, and broken user databases. If your application handles transactions, you need an API backend that is secure, resilient, and fully automated.

I am a backend software engineer specializing in financial data flows and payment gateway integrations. I build custom, secure checkout experiences and bulletproof webhook handlers that ensure your app never drops a transaction state.

Expertise I Build Into Your Application:

• API Integrations: Flawless implementation of Paystack API and Stripe SDKs for standard, split, or automated marketplace checkouts.
• Secure Webhook Handlers: Production-grade webhook routes built with cryptographic signature verification to block malicious spoofing attempts.
• State Management: Instantaneous database syncing (PostgreSQL, MySQL, MongoDB) to automatically update user permissions or order tables post-purchase.

Idempotency & Fail-Safes: Structuring logic to prevent double-billing on network timeouts and setting up custom retry loops for internal server drops.
