About this gig

Is your Stripe integration charging customers twice, missing webhook events, or breaking under traffic? I fix it fast.

I'm a backend engineer working on production banking systems where payment reliability isn't optional. I've debugged webhook race conditions, idempotency failures, and dead-letter scenarios that cost real money to get wrong.

What I fix:

Duplicate charges from missing idempotency keys

Webhook events firing twice or not at all

Race conditions between webhook delivery and customer redirect

Failed signature verification

Webhook timeouts and Stripe retry storms

Production webhooks working in test mode but failing live

My approach:

1. You send me your code, error logs, and Stripe dashboard webhook event history

2. I reproduce the issue in test mode

3. I fix it with proper idempotency, validation, and error handling

4. I document what was wrong and how to prevent it next time

Tech I work with: Node.js, NestJS, Express, TypeScript, PostgreSQL, Stripe API (latest version)
