Built to learn Stripe's API properly. Full checkout flow, webhooks, subscription billing, and a Sidekiq-backed fulfillment queue. Runs on Fly.io.
I'd integrated Stripe in projects before, but always through a higher-level library that abstracted away the webhook handling, idempotency keys, and event ordering. I wanted to understand the primitives.
So I built a demo webshop from scratch: product catalogue, cart, checkout, Stripe Checkout redirect, webhook receiver, fulfilment queue, and a basic admin. No shortcuts.
No open slots right now — but reach out and I'll add you to the waitlist.
