This work covers operational systems supporting multi-channel e-commerce sales. Source code and configurations are private due to commercial and platform restrictions.
Context
E-commerce operations spanning Amazon FBA, Shopify, and third-party fulfillment tools
Need for consistent product data, inventory visibility, and order tracking across platforms
Manual processes increased risk of listing errors, fulfillment delays, and inventory mismatches
Constraints
Each platform enforced its own APIs, workflows, and operational limitations
Inventory and fulfillment logic needed to align with Amazon FBA rules and Shopify order flows
Operational reliability was more important than real-time synchronization
Solution
Set up centralized product and inventory workflows using Shopify as the operational hub
Integrated Amazon FBA and multi-channel fulfillment to route eligible orders automatically
Standardized SKUs, listings, and fulfillment settings to reduce operational inconsistencies
Built reporting and monitoring processes to track orders, inventory status, and exceptions
Key Decisions
Chose platform-native tooling where possible to reduce maintenance overhead
Prioritized consistency and correctness over real-time inventory updates
Kept fulfillment logic simple to minimize edge cases during scaling
Impact
Improved inventory accuracy and reduced fulfillment-related errors across channels
Lowered manual operational effort required to manage listings and orders
Enabled smoother scaling of new products without reworking core workflows
