Amazon seller e-commerce platform

The client had specific requirements that existing tools didn't meet. Their business logic was custom: the way they managed products, priced items, and tracked orders didn't map neatly to any available platform. Adopting one would have kept them in the pattern they were trying to leave — separate tools that don't talk to each other, and duplicate work to keep them aligned. A custom build was the right call.

We built a connector that synced product listings, inventory levels, and order status between the client's platform and Amazon's Selling Partner API. Changes made in the platform reflected on Amazon automatically. Orders from Amazon flowed back into the platform for fulfillment. The entire sync loop ran without any manual intervention from the client, so listings did not have to be re-keyed and orders did not have to be tracked separately.

The client had specific expectations — clean architecture, documented code, testable components. We assigned developers who were comfortable working inside those constraints without needing constant supervision, so meeting the standard did not depend on the client policing it. The client reviewed the code and found it met their standards from the start.

We gave the client proactive updates, so they didn't have to ask where things stood. The team flagged issues before they became blockers, researched edge cases the client hadn't thought of, and communicated changes clearly. In the client's own account of the engagement, they never had to chase us for updates.
