About this gig

Tired of stockouts, overselling, and manual order fulfillment across multiple channels? I build custom, high-speed API integrations to sync your stores in real time.


As a full-stack e-commerce developer, I connect Shopify, Amazon, and eBay using robust APIs and cloud middleware to automate your catalog, inventory, and order flows.


What I Do:

  • Multi-Channel Sync: Real-time inventory and pricing sync across Shopify, Amazon, and eBay
  • Custom API Integrations: Shopify GraphQL/REST Admin API, Amazon SP-API, eBay REST API
  • Secure Authentication: OAuth 2.0 setup, LWA token generation, automated token rotation
  • Advanced Data Flow: Webhooks, AWS Lambda/SQS queues, and rate-limit handling to eliminate errors
  • Custom App Development: Bespoke Python and PHP/Laravel microservices for warehouse & 3PL routing


Why Choose Me?

  • Sub-second stock update architecture
  • Clean, maintainable, and scalable code
  • Reliable sandbox and production deployment


Stop losing sales to mismatched inventory. Message me today to discuss your integration needs before placing an order!
