Anonymised client integration · Pilot / testing
Connecting order workflows across business systems.
Commerce ↔ ERP · Client integration work between an e-commerce platform and an ERP. This overview describes the engineering workflow without identifying the client or exposing business data.

The problem
An e-commerce order has to be translated into the ERP’s business model. The work involves authentication, mapping and processing failures as well as moving data between APIs. Each system has its own interface and expectations.
Conceptual flow, simplified for this case study.
My contribution
My work covers the Python / Django integration service, API adapters, order-data mapping, background processing, testing and operational diagnostics.
- Connecting the platform APIs through separate adapters
- Mapping order data to the receiving system’s model
- Testing exchanges and investigating processing failures
Engineering decisions
Separate the adapters from the workflow
Platform-specific authentication and API behaviour belong in adapters. Keeping them separate from order mapping makes it possible to reason about the business workflow without mixing in every transport detail.
Make processing inspectable
Background processing and operational diagnostics are part of the implementation. When an exchange fails, the integration needs enough context to investigate the affected step and its data mapping.
Why it matters
The focus is a workflow that can be inspected and tested across system boundaries. The value of the approach is in understanding how an order moves through the integration and where an exchange needs attention.
Current status
The project is in pilot integration and testing, with implementation and verification of the order workflow in progress.
