Project: Server-Side Tracking Setup — WordPress Site

Overview
I need a freelancer to set up server-side tracking on my WordPress site (Hostinger, Cloudflare). The goal is to have all pixels firing accurately so my ad campaigns can optimize effectively — and so my audience data is already building before I scale advertising next year.
Platforms to Track

Google Tag / GA4
Bing (Microsoft) Ads
Meta Pixel
X (Twitter) Pixel
TikTok Pixel

Requirements

Server-side implementation so data collection is not affected by ad blockers or browser-based tracking restrictions
Conversion events must fire correctly — page views, key engagement actions, and any form submissions or sign-ups
No existing tracking scripts on the site — this is a clean installation
You choose the best technical approach (Zaraz, GTM, or combination) and explain your reasoning before starting

What I Need From You

All five pixels installed and verified firing
Conversion events confirmed in each platform's native dashboard
Brief handoff note explaining what was set up and how to add new events in the future

Budget: $100 fixed price
To Apply: Tell me which approach you would use (Zaraz, GTM, or other), why, and whether you have done server-side tracking on WordPress before.
