High-Volume E-Commerce & Retail Systems
When standard Shopify apps and WooCommerce plugins become an unstable, expensive patchwork, we engineer enterprise headless commerce backends built for 100,000+ daily orders with automated courier COD audit.
Why off-the-shelf stores break at scale
Campaign Traffic Spikes Crashing Shopify / WooCommerce
During major marketing campaigns or flash sales, database connection exhaustion brings down monolithic storefronts, resulting in thousands in lost sales and angry buyers.
Inventory Overselling Across Multiple Warehouses & Retail Stores
Selling the same physical stock concurrently across website, physical retail outlets, Daraz/Amazon, and WhatsApp leads to cancellation calls, refunds, and damaged brand reputation.
Cash-on-Delivery (COD) Courier Reconciliation Nightmare
Tracking tens of thousands of COD packages across multiple courier providers (TCS, Leopards, Trax, PostEx). Discrepancies between courier remittance sheets and actual bank credits go unnoticed for months.
High Return-to-Origin (RTO) and Fake Order Frauds
Fake buyer phone numbers and non-serious orders generating massive reverse logistics freight penalties without automated verification checks before fulfillment.
The Headless Commerce & COD Auditor Blueprint
Engineered with Redis distributed locks, PostgreSQL partitioned order tables, and direct REST integrations with leading regional courier APIs.
High-Concurrency Headless Checkout Engine
Decoupled Go/Node.js checkout service capable of processing 5,000+ orders per minute with atomic inventory locks and sub-second payment gateway response.
Real-Time Multi-Warehouse Stock Synchronizer
Centralized inventory ledger synchronizing physical retail POS terminals, central fulfillment centers, and third-party marketplace channels within 200 milliseconds.
Automated Multi-Courier Gateway & COD Auditor
Single unified API integrating all major couriers. Automatically selects cheapest/fastest courier per destination and matches daily courier bank remittances line-by-line.
Predictive RTO Fraud & Address Sanitization
Automated WhatsApp OTP verification for new COD buyers, address deduplication, and historical risk scoring to flag high-probability fake orders before dispatch.
Warehouse Barcode Wave Picking & Pack Verification
Optimized picker routing algorithms in the warehouse with barcode scan verification at packing tables to ensure 100% correct items in every dispatch bag.
Real-Time Operational Financial Ledger
Real-time profit-and-loss calculation per SKU: calculating gross margins after factoring in ad-spend attribution, packaging costs, and courier delivery fees.
