About this gig

Tired of repetitive tasks eating into your day? Let's automate your Shopify store.

I build Shopify backend automation and API integrations that sync your data, connect your tools, and take busywork off your plate so you can focus on growing the business.


What I'll build for you:


  • Custom backend automation flows
  • Third-party API integration
  • Automated data sync & imports
  • Order & customer management via API
  • Custom Payment Integration
  • Webhook setup & cron jobs
  • CRM and email tool connections
  • Clean, documented code


Every build comes with proper error handling and documentation, so nothing breaks the moment I deliver. Happy to show a live demo first.


Message me before placing your order and I'll review your requirements at no cost.


Tech Stack: Node.js, JavaScript, Express, Shopify Admin API, Webhooks, REST APIs, MongoDB, OAuth.

I'm an API developer who helps businesses connect their tools and automate the work that slows them down. I specialize in API integration and backend automation, linking stores, apps, and platforms with payment gateways, CRMs, and third-party services so your data flows on its own. Every project I deliver comes with clean code, error handling, and clear documentation, so nothing breaks after handover. I'd rather build something reliable than something rushed. Have a project in mind? Message me and let's talk it through.
