Indian E-commerce Website End-to-End Testing

I'm seeking a seasoned QA professional team to conduct comprehensive end-to-end testing on my e-commerce platform before its launch. The site and its mobile counterparts (Android and iOS) are designed with various features that need meticulous verification.

Key Testing Aspects:

- User Authentication: Although I skipped confirming the specifics, the platform supports registrations and logins via Email, Google, and OTP. All these routes need to be tested for functionality and security.
- Product Catalog: The filtering and sorting mechanisms in the product catalog must work seamlessly.
- Shopping Cart and Checkout: This includes testing the interactions with various payment gateways such as UPI, Credit/Debit Cards, and Cash on Delivery (COD).
- Order Tracking and Customer Dashboard: Both components should provide accurate information and updates.
- Admin Panel: The interface for inventory and order management needs to be verified for usability.
- Basic CMS: The blog and content management system should function without errors.

Looking forward to your proposals.
