Marketplace & E-Commerce Engineering

Production marketplace operations. Not just an integration — the whole backend.

We build and operate the engineering that connects e-commerce businesses to Amazon, eBay, Walmart, Newegg, and every marketplace in between.

What we build

The backend machinery that makes multi-marketplace selling work at scale. Not a plugin — custom-built integration layers that handle the edge cases, rate limits, and API version changes that break generic solutions.

  • Amazon SP-API integration — catalog sync, order management, inventory feeds, buybox monitoring, repricing logic
  • ChannelAdvisor automation — custom workflows, feed management, inventory rules, cross-channel sync
  • eBay, Walmart, Newegg, Houzz — listing management, order import, fulfillment sync
  • Supplier catalog ingestion — extracting and normalizing product data from hundreds of distributor feeds
  • Custom order processing — ERP integration, RMA workflows, fulfillment routing
  • Shopify and BigCommerce custom app development

Production at scale

Our longest marketplace engineering engagement exceeds a decade. 125+ automated backend programs run continuously — catalog sync, price updates, order routing, inventory reconciliation, marketplace compliance checks. This is operations-grade engineering, not project-based integration work.

When this is the right fit

  • You sell on multiple marketplaces and need a unified backend
  • Your catalog has thousands of SKUs from dozens of suppliers
  • You need custom repricing, buybox tracking, or competitive intelligence
  • Generic marketplace tools have hit their limits
  • You need reliable automation that runs unsupervised

Need a marketplace integration that actually works?

We'll scope the API coverage, estimate the build, and ship a pilot in weeks.
