Overview
A distributed tracking system connecting warehouses, carriers, and customs checkpoints across multiple regions. Each shipment emits a stream of state transitions that must remain ordered, auditable, and queryable across services.
Services are deployed as containerized units behind an API gateway, with event-driven synchronization between the relational core (inventory, orders) and document stores (raw tracking logs).
Key Results
- [01]Shipment state machine covering 20+ lifecycle transitions across 5 regional clusters.
- [02]Idempotent webhook ingestion for carrier integrations with automatic replay.
- [03]Containerized CI/CD via GitHub Actions — zero-downtime rolling deploys.
- [04]Inventory reconciliation job that flags discrepancies before end-of-day close.
