About Shaun
I help e-commerce businesses fix broken payment and checkout systems that directly impact revenue.
Many online stores rely on interconnected systems like Shopify, Stripe, and backend APIs. When these systems fail to communicate correctly, it leads to lost payments, missing orders, or broken checkout flows.
I specialize in diagnosing and resolving these issues across payment integrations, webhook systems, and e-commerce infrastructure.
My work typically involves Adyen, Stripe, or Shopify integrations, checkout debugging, and fixing data flow issues between payment providers and backend systems.
With a background in payment implementation and system-level troubleshooting, I focus on restoring reliable revenue flow across complex e-commerce setups.
