Laravel+Next.js Dev for PayPal-Apple Integration Fix

I’m looking for an expert Laravel + Next.js developer who has strong experience with PayPal Advanced Checkout, especially Apple Pay through PayPal.

My website already has PayPal, cards, and Google Pay working. The issue is specifically with the PayPal Apple Pay integration. I need someone to properly diagnose the current implementation, find the exact reason Apple Pay payments are not being captured/detected correctly by PayPal, and fix it fully.

The goal is simple: Apple Pay must work 100% correctly through PayPal, the same way Google Pay and card payments work on my website.

What I need:
Review my existing Laravel backend and Next.js frontend code
Diagnose the PayPal Apple Pay flow completely
Fix Apple Pay payment creation, authorization, confirmation, and capture
Make sure payments are actually charged and visible inside PayPal
Make Apple Pay work correctly in both sandbox and live mode
Keep the existing PayPal, card, Google Pay, order, checkout, and capture logic untouched unless absolutely necessary
Match the official PayPal Apple Pay documentation
Test the full checkout flow after the fix
Explain clearly what was wrong and what was changed
Required skills:
Laravel expert
Next.js expert
PayPal Advanced Checkout experience
Apple Pay integration experience
Strong debugging skills
Experience with payment capture flows
Ability to work with existing code without breaking other payment methods
Important:

Please do not apply if you only have basic PayPal integration experience. I need someone who understands PayPal Apple Pay specifically, including how PayPal handles Apple Pay orders, tokens, captures, and live/sandbox environments.

The final result must be a fully working Apple Pay checkout where the customer is charged successfully and the order is processed correctly on my website.
