Need help fixing bugs or connecting APIs in your Shopify app?


I troubleshoot and improve Shopify apps built with React, Node.js, TypeScript, and Shopify APIs.


I can help with:

- Fixing frontend, backend, embedded app, and Shopify API issues

- Third-party API integrations, webhooks, authentication, and data syncs

- Product, cart, discount, checkout, and admin workflow bugs

- Debugging app extensions, performance issues, and deployment problems

- Refactoring React and Node.js code for stability and maintainability


Please message me before ordering with your app URL, bug details, steps to reproduce, error messages, and relevant API or repository access.
