I will do stripe integration, stripe connect, subscriptions and webhooks


About this gig
Payments have a lot of edge cases: declined cards, 3D Secure, webhooks that arrive late or twice. I'm a senior Ruby on Rails engineer with eight years of experience, and I have integrated Stripe, PayPal and other providers into Rails apps and SaaS platforms.
PROVIDERS I WORK WITH
- Stripe, including 3D Secure
- PayPal
- Apple Pay and Google Pay
- Amazon Pay
- Checkout
WHAT I CAN DO
- Stripe Connect payouts for marketplaces
- Stripe subscriptions, trials and billing changes
- Add card payments or checkout to your Rails app
- Add or fix 3D Secure flows
- Add wallets such as Apple Pay and Google Pay
- Handle provider webhooks so your records stay in sync
- Fix payment flows that fail or behave inconsistently
- Cover the payment code with RSpec or Minitest tests
HOW IT WORKS
- Message me with your provider, your app's stack and what you need.
- I confirm scope, price and delivery time before you order.
- I build and test in the provider's test mode. You add your live keys when you deploy.
I also built and run Hajza, a booking and point-of-sale platform live with paying venues, where every bill has to agree to the cent.
Please message me before ordering so I can confirm the details.

Yes. Send me the error or the step that fails and I'll review the code before quoting.
