Optimize Laravel E-commerce Website Speed + Fix Meta Pixel Error + Setup GA4 & FB Pixel Server-Side Tracking -- 2

Description:
I have an e-commerce website: www.beauti4me.com
(Laravel based). Currently, I am facing some technical issues and I need a professional freelancer to handle them:

Problems to Fix:

Website Speed Optimization

The website loads very slowly. I need a full optimization (frontend & backend) to improve page speed, Core Web Vitals, and overall performance.

Meta Pixel Issue

I have already set up the Facebook Pixel. Data is received in Event Manager, but the FB Pixel Helper browser extension shows errors.

After a hard refresh, the error disappears. I need this fixed permanently.

Server-Side Tracking Setup

Complete setup of Facebook Pixel (Server-Side API) with all important e-commerce events (ViewContent, AddToCart, InitiateCheckout, Purchase, etc.).

Setup Google Analytics 4 (GA4) Server-Side Tracking with necessary conversion events.

Remove all previous pixel and analytics setups to avoid duplication or conflict.

Requirements:

Strong experience in Laravel, GTM, Meta Pixel, GA4, and Server-Side Tracking.

Must deliver error-free integration with correct event firing & verification via FB Pixel Helper and GA4 Debug View.

Ensure fast loading speed (both mobile & desktop).

Provide clear documentation of the implementation.

Deliverables:

Fully optimized & faster Laravel website.

Correct FB Pixel setup without browser extension errors.

Server-Side Tracking for both FB & GA4 with tested events.

Removal of all old/duplicate tracking codes.

Final testing & proof of correct implementation.
