Jack The Jelli is a leather goods brand in Dhaka. The job was the whole store: storefront, cart, cash-on-delivery checkout, order tracking, customer accounts and an admin back-office, in a single Next.js 16, TypeScript and MongoDB codebase.
Araf took it from an empty repository to a live store taking nationwide orders in two months, as the only engineer on it.
Order placement was designed to stay correct when things go wrong:
| What could go wrong | What stops it |
|---|---|
| The same order arrives twice | Idempotency keys block duplicate orders. |
| A cancellation puts stock back more than once | Guarded atomic decrements restore stock exactly once on cancellation. |
| A product is edited after it was ordered | Snapshotted line items stop later product edits rewriting order history. |
The checkout is public and unauthenticated. It runs on rate-limited server actions, and delivery is priced on the server, across all 64 districts. Guests can order without an account, and their orders attach to one on email verification.
Launch infrastructure cost came to effectively zero: Araf persuaded the founders to defer the payment gateway, AI search and third-party APIs until after scale.
