Problem Solving
Challenges We Tackled
Every project presents unique challenges. Here's how we approached and solved the key technical hurdles.
Multi-Vendor Payment Splitting
Each order may contain products from multiple vendors, requiring automatic payment splitting and commission calculation.
Integrated with payment processors supporting connected accounts. Automated commission calculation and instant payouts to vendor accounts with detailed transaction records.
Inventory Synchronization
Vendors sell on multiple channels, requiring real-time inventory sync to prevent overselling.
Event-driven inventory system with webhook integrations for external channels. Reservation system holds stock during checkout to prevent race conditions.
Search and Discovery
Customers need to find products across thousands of vendors with personalized results.
Elasticsearch powers product search with faceted filtering, typo tolerance, and synonym handling. Machine learning model provides personalized rankings based on user behavior.
Scalability for Peak Traffic
Sales events and promotions cause 10x traffic spikes that must be handled without degradation.
Auto-scaling Kubernetes deployment with Redis caching layer. CDN for static assets and API response caching for common queries.
