E-commerce API
A RESTful API built for inventory management, payments, and order fulfillment at scale.
A commerce backend handling catalogue, inventory reservation, payments, and fulfilment webhooks for a multi-warehouse retailer.
The hard part was consistency: keeping stock counts honest across concurrent checkouts while staying fast enough for a busy storefront.
Highlights
- Idempotent checkout flow with Stripe payment intents
- Row-level inventory reservations to prevent oversell
- Webhook processing with retries and dead-letter handling
