About this gig

I develop custom Shopify apps (private or public) using Shopify Admin API, GraphQL, REST APIs, Webhooks, and secure OAuth authentication. If Shopify's native features cannot solve your business workflow, I build scalable, production-ready solutions tailored to your needs.


I specialize in:

  • ️ Shopify Private or Public App Development
  • ️ Admin API & GraphQL Integrations
  • ️ Webhooks & Automation
  • ️ Subscription Logic & Billing APIs
  • ️ Inventory, Orders, Products & Customer Automation
  • ️ Third-Party API Integrations (ERP, CRM, Shipping, Payments)
  • ️ Custom Dashboards & Backend Logic
  • ️ Performance Optimization & Security


Whether you need automation, system integrations, advanced logic, or custom workflows, I deliver clean architecture and reliable performance.


Why Me:

  • Deep Shopify API Expertise Admin API, GraphQL, REST, Webhooks
  • Scalable Architecture Clean, maintainable, production-grade code
  • Security First OAuth, token handling, secure webhooks
  • Business Logic Focused Not just code, but operational efficiency
