Architectural Overview
A resilient backend data synchronization service designed to bridge legacy ERP inventory systems and modern web/storefront applications.
Technical Challenges Solved
- Preventing race conditions and duplicate writes during concurrent inventory updates.
- Handling third-party API rate limits and intermittent connection drops gracefully.
- Logging transactions and errors with structured audit trails for operational monitoring.
Implementation Highlights
- Implemented exponential backoff retry mechanisms and dead-letter queue patterns.
- Engineered transactional database operations ensuring strict data integrity across inventory adjustments.
- Created RESTful administration endpoints for monitoring sync health and triggering manual reconciliations.
- Packaged service with comprehensive automated unit tests and Dockerized deployment configurations.
