About This Project
Engineered a multi-warehouse routing engine to optimize order fulfillment across distributed inventory centers. Integrated real-time shipping APIs with concurrent request handling to minimize latency. Developed custom inventory logic for complex product types and implemented robust fallback mechanisms to ensure 100% system availability during third-party API outages.
Technologies Used
Engineering Challenges
Inventory Dependency Logic: Solved the challenge of tracking 'virtual' stock for kits and custom-cut items that do not hold independent inventory. Implemented a recursive validation system that calculates availability in real-time based on parent component stock levels.
Logistics Optimization: Designed an algorithm to handle split-inventory orders, dynamically grouping items to reduce shipping costs and transit times while adhering to specific business constraints for vendor-shipped and backordered goods.
Performance at Scale: Addressed high-latency issues inherent in sequential API calls by implementing a concurrent request architecture, reducing processing time by over 75% during the checkout phase.
Technical Highlights
Concurrent API Integration: Utilized parallel cURL processing to query multiple logistics endpoints simultaneously, achieving sub-second response times for complex warehouse ranking operations.
Data Normalization Layer: Built a robust preprocessing engine to sanitize and format geographic data, ensuring high success rates for third-party API address validation and rate requests.
Resilient Architecture: Designed a 'Graceful Degradation' strategy that detects external service failures and automatically switches to an internal fallback ranking system, maintaining a seamless user experience.
Business Logic
Direct-to-Consumer Routing: Automated the detection and exclusion of vendor-managed (dropship) items from internal consolidation to streamline fulfillment.
Intelligent Backorder Handling: Developed logic to isolate out-of-stock items to primary distribution hubs, preventing unnecessary transshipments and reducing overall delivery lead times.
Hybrid Fulfillment Rules: Created a specialized 'Will-Call' workflow that allows for immediate local pickup of available stock while automatically coordinating the consolidation of remaining order items.
