Overview

Business infrastructure for a company that was running orders, invoices and support out of spreadsheets. The hard part was not the CRM; it was making money movement reconcile reliably.

I built the customer-facing checkout flow, the Razorpay webhook handling with retry and idempotency, server-rendered PDF invoices, and an admin console where ops and support manage customers, orders and refunds.

What I built

  • Idempotent Razorpay webhook handling with reconciliation against local order state
  • Server-rendered PDF invoices delivered by transactional email on checkout
  • Admin console for ops: customers, orders, invoices, refunds, and manual overrides
  • Retry and refund paths covered explicitly rather than left to support tickets
