The Job

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.

How it was done

Orders that stay correct under failure

Order placement was designed to stay correct when things go wrong:

What could go wrongWhat stops it
The same order arrives twiceIdempotency keys block duplicate orders.
A cancellation puts stock back more than onceGuarded atomic decrements restore stock exactly once on cancellation.
A product is edited after it was orderedSnapshotted line items stop later product edits rewriting order history.

A public checkout, hardened

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.

Nothing paid for before it was needed

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.
