About this gig
Your Shopify store has a problem no theme seller can fix. I can.
As a Shopify developer and expert in backend work, I do what most sellers can't real API integration, payment gateways, webhooks, and checkout logic, including Shopify Plus stores. If your store is broken or you need a custom feature built, you're in the right place. I start fast on urgent fixes and go deep on the technical builds that need real engineering.
Services I offer:
- Shopify bug fix
- figma to shopify / psd to shopify
- Shopify liquid
- Shopify custom code
- Shopify customization
- shopify CRO
- Shopify liquid code
- shopify headless / hydrogen
- Shopify theme customization

- Shopify app integration
- shopify custom app development
- Shopify checkout fix
- Checkout page
- Shopify store setup
- Shopify speed optimization
- Shopify migration
- Shopify redesign

Why me: backend, API, and payment expertise (Python / FastAPI), not commodity theme design. I test everything before delivery & communicate clearly with updates throughout.

FAQ
What kind of Shopify work do you handle?
I cover the full range, from a quick Shopify bug fix or fix Shopify errors, through Shopify liquid, custom code and theme customization, up to Shopify API integration, payment integration and Shopify Plus checkout work. including Shopify coding, custom coding Shopify or Shopify liquid code, i can do
My store is broken, how fast can you fix it?
Most urgent issues like a Shopify bug, a broken checkout page, a Shopify checkout fix, I turn around in about a day. Send your store URL and a description of the problem and I'll confirm scope before you order. Deeper Shopify customization and custom code builds take a little longer
Can you integrate payments and third-party apps?
Yes this is my core strength. Shopify payment integration, Stripe integration, PayPal integration, and payment gateway setup, plus Shopify third party integration, Shopify webhook work, and Shopify app integration. Real backend work most theme-only sellers can't do
Do you work on Shopify Plus and custom checkout?
Yes. Full Shopify checkout customization needs Shopify Plus, so if you're on Plus I can customize the checkout page directly. If you're not sure of your plan, tell me before ordering and I'll confirm exactly what's possible for your store.
Can you build or set up a store from scratch?
Yes i handle Shopify store setup, Shopify migration from another platform, Shopify redesign, and Shopify landing page builds. Whether it's a fresh store or moving an existing one over, I make sure it's clean, tested, and ready to sell.
Can you make my store faster?
Yes ! Shopify speed optimization is a regular service. Slow stores lose sales, so I diagnose what's dragging your load times and fix it, often alongside a Shopify redesign or theme customization pass to tighten the whole store.
What happens after delivery?
I test everything before handing it over and communicate clearly with updates throughout. I also offer ongoing Shopify support for clients who want a developer on call for future changes rather than a one-off fix.
