About this gig
Need a Shopify developer to fix a theme issue, build a custom feature, or connect your store to another system?
I'm David. I work with Shopify custom coding, Liquid, JavaScript, and API integrations to solve specific store problems.
I can help with:
- Theme customization and responsive layout fixes
- Custom sections, product-page features, and cart interactions
- Shopify API integration with a CRM, inventory tool, or external service
- Scoped order, product, or customer data workflows
Choose a small code fix, a custom theme feature, or a one-way API integration. I'll confirm the scope, implement the agreed work, test it, and provide a clear handover. Theme changes are prepared in a duplicate theme where possible.
Integration pricing covers one external service, one data type, and one agreed workflow. Two-way sync, large migrations, public apps, and complex ERP projects need a custom quote. Paid apps, hosting, and third-party fees are separate.
Message me with your store URL, the result you need, and any API documentation before ordering so I can recommend the right package.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

FAQ
Should I contact you before ordering?
Yes. Send your store URL, the change you need, and any relevant screenshots or API docs. I will check feasibility and confirm the scope, price, and delivery time before you order.
What does each package include?
Basic covers one small theme fix. Standard covers one custom section or scoped theme feature. Premium covers one one-way API workflow with one external service and one data type. The page count refers to the affected template, not a full store build.
What Shopify custom coding can you help with?
I can customize Liquid templates, responsive layouts, product pages, sections, and cart interactions. Share the behavior you want so I can check your theme and any app conflicts before quoting.
Which API integrations can you build?
I can connect Shopify with a CRM, inventory tool, or other service with a suitable API. Premium includes one data type and one-way sync. Two-way sync, historical imports, multiple systems, and complex ERP work need a custom quote.
Will you change my live store?
Theme work is prepared in a duplicate theme where possible, then shared for review before publishing. API integrations are tested with agreed test data or a sandbox where available. We agree any live changes before deployment.
Are apps, hosting, or subscriptions included?
No. Shopify plans, paid themes, paid apps, hosting, and third-party API fees are paid by you. I will identify required services before we agree the project. You keep ownership of your store and service accounts.
Can you customize Shopify checkout?
Checkout options depend on your Shopify plan and the extensions Shopify allows. Send your plan and requirements first. I will confirm what is feasible before accepting the work.
What counts as a revision?
A revision adjusts the agreed deliverable within the original scope. Basic includes 1 revision, Standard and Premium include 2. New features, extra templates, new systems, or a different data flow require a separate quote.
What access and materials do you need?
I need your requirements, relevant assets, and appropriate Shopify collaborator access. API projects also need API documentation and authorized access to the external service. Please do not send your account password.
Are the gallery images completed client projects?
The gallery illustrations show example services and concepts. The attached PDF is my broader web-development portfolio. It shows design and development work, not a claim that every project used Shopify or included an API integration.
