Depoters WMS
End-to-end Warehouse Management System supporting inventory, warehouse, order, and fulfillment operations.
The problem
Multi-client warehouses needed one modular system for inventory accuracy, order throughput, and automated dispatch.
- Modular Node.js/Fastify services for inventory, warehouse, order & fulfillment
- Reusable REST APIs + data pipelines for bulk catalog imports & external sync
- Custom warehouse rule engines
- Geofencing-based order routing
- Automated dispatch workflows
Engineering challenges
· Bulk catalog ingestion at 50K+ SKU scale
· Sustaining 2K+ daily orders with 99.8% accuracy
· Per-client warehouse rules without forking the codebase
Architecture
Fastify services → MongoDB → React.js ops console → external system sync pipelines
Order Easy
B2B platform syncing agrochemical manufacturers, distributors, and retailers.
The problem
Agrochemical supply chains needed synced catalogs, scheme hierarchies, and reliable order/CN workflows across manufacturers, distributors, and retailers.
- Manufacturer / distributor / retailer synchronization
- CN calculation engine
- Scheme hierarchy management
- Workflow engines for B2B order flows
Engineering challenges
· Multi-tier pricing & scheme hierarchies
· Correct CN calculation across order workflows
Architecture
Node.js + Fastify API layer → relational/document stores → React.js B2B frontend
Flickd Social Commerce App
Mobile social commerce app combining social discovery with commerce experiences.
The problem
Shoppers wanted social discovery and fast checkout in one mobile experience; merchants needed synced catalogs and automated flows.
- 20+ React Native screens: feeds, discovery, profiles, transactions
- Shopify catalog sync + checkout
- WooCommerce catalog sync + checkout
- Merchant automation integrations
- Optimized rendering + streamlined checkout
Engineering challenges
· Native commerce UX across 20+ screens
· Reliable Shopify/WooCommerce sync + checkout
Architecture
React Native client → REST APIs → Shopify / WooCommerce integrations
