Automated Inventory & Order Syncing for Canadian Retailers
Eliminate overselling, stockout penalties, and manual spreadsheet updates across multiple sales channels. Mr Umer Malik builds custom inventory synchronization engines and warehouse microservices for Canadian multi-channel retailers in Toronto, Vancouver, Montreal, and Calgary. Connect your Shopify, Amazon Canada, Walmart Canada, and brick-and-mortar POS systems with real-time atomic inventory locks and sub-second updates.
Core Capabilities & Production Deliverables
Direct architectural execution by senior engineer Mr Umer Malik with zero agency dilution.
Real-Time Multi-Channel Stock Synchronization
Automated event-driven webhooks updating inventory levels instantly across Shopify, Amazon Canada, eBay, and wholesale portals.
Atomic Inventory Reservation Locks
Prevent accidental overselling during high-volume sales by holding temporary stock reservations during the checkout funnel.
Multi-Warehouse & Regional Routing
Intelligent order routing algorithms that split line items based on stock availability in Ontario, Alberta, and British Columbia warehouses.
POS & ERP Middleware Connectors
Custom connectors synchronizing stock levels with Lightspeed POS, Square, NetSuite, SAP, and Cin7 in real time.
Automated Low-Stock & Reorder Alerts
Configurable threshold monitors notifying purchasing managers via Slack or email when inventory drops below safety thresholds.
Resilient Asynchronous Message Queues
RabbitMQ and AWS SQS message queues ensuring that transient API rate limits or network drops never cause missed inventory events.
