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 Private & Public App Development
- API Integration (SMS, Courier, Payment, etc.)
- App Publishing & Configuration Support
- Custom Features Development
- UI/UX Optimization for Shopify Apps
