03 — Implementation
Key Engineering Decisions
- Developed strongly typed DTO validation pipelines to ensure incoming order schemas meet fulfilment specifications.
- Implemented resilient retry queues with exponential backoff for handling third-party API downtime.
- Constructed audit logging to track order lifecycle states from creation through fulfilment acknowledgement.
- Packaged the service with Docker for containerized deployment in Linux server environments.
04 — Results & Value Delivered
Outcome & Operational Impact
Standardised order processing between the e-commerce platform and fulfilment operations, eliminating manual exports and reducing order processing latency.
