About this gig

Got an app that won't cooperate with your Shopify store?


I handle third-party app installations, custom API integrations (REST and GraphQL), and full B2B/B2C store configurations including wholesale pricing rules, customer-tagged access, and checkout customizations. I debug conflicting apps, fix broken webhooks, and connect external systems your developer "almost" got working.


Whether you're running a B2B wholesale portal with tiered pricing or a high-volume B2C store with loyalty and subscription integrations I've handled it. You get a fully working setup, not a "should be fine" handoff.


What I Can Do For You

  • Custom Shopify App Development
  • Shopify API Integration (REST & GraphQL)
  • Shopify Functions (Discounts, Cart, Checkout)
  • Third-party API Integration
  • Private & Public Shopify Apps
  • Shopify App Bug Fixing & Optimization
  • Shopify Checkout Extensibility
  • Shopify Automation & Custom Features
  • Shopify Private & Public App Development
  • API Integration (SMS, Courier, Payment, etc.)
  • App Publishing & Configuration Support
  • Custom Features Development
  • UI/UX Optimization for Shopify Apps


Send me a message and lets discuss your project before placing an order.

    Working with Samuel was genuinely refreshing. From the first message it was clear I wasn't dealing with someone who just follows instructions, he actually understands Shopify at a deep level.
