Shopify Checkout & Mobile Tweaks

I recently built a Shopify-based eCommerce website and completed A/B testing. I discovered a small issue in the checkout/payment process that needs debugging and fixing.

The website works well overall, especially on desktop. However, there are a few minor layout issues on mobile that need simple adjustments. This is not a redesign — only small responsive improvements.

The total budget for this task is $20, so I am looking for someone who can quickly identify the issue and fix it efficiently.

Tech Stack:

The frontend is built using React with TypeScript. The backend is developed with NestJS, and PostgreSQL is used as the database. The project also includes Shopify payment integration for checkout processing.

Scope of Work:

You will debug and fix the payment issue occurring during checkout and ensure that orders are processed correctly after payment. You will test the current Shopify integration to confirm everything works properly. In addition, you will make minor responsive adjustments on mobile devices, such as fixing spacing, alignment, or button sizing issues. The desktop design should remain unchanged.

Requirements:

You should have experience working with Shopify payment integrations and be comfortable debugging React and NestJS applications. You must be able to test the current system, identify the root cause of the issue, and implement a clean fix quickly. Fast turnaround and clear communication are important for this small task.

I will share the source code and full details once the project begins.
