The operating context
A Saudi specialty-coffee commerce platform built around mobile discovery, ordering and fulfilment.
Engineering focus
Consumer commerce is judged on the checkout and remembered by the order status. The engineering work concentrated on the ordering path: keeping product and stock data accurate at the moment of purchase, handling payment and order confirmation as separate states so a failed callback never leaves a customer charged without an order, and passing a clean, complete order into fulfilment. Mobile networks drop, so retries had to be idempotent — a repeated request must not create a second order.
Why it matters
The visible product is a short, simple journey. What keeps it simple is everything underneath: one authoritative order state, predictable stock behaviour under concurrency, and an operational view that lets the business answer "where is my order?" without inspecting the database.
This page describes selected engineering experience. Where work predates Nerve & Keel, it is presented as team-member experience rather than as a Nerve & Keel client engagement.
