WordPress + VPS/PHP Expert Needed, URGENT Debug, Performance Fix

We need an experienced WordPress full-stack developer with VPS/server expertise to urgently fix performance issues on our custom WordPress site (persiscollection.com).

About the Site:

Built on a custom WordPress theme (not using page builders).

Many custom-coded functions (WooCommerce, customer club, shipping rules, dynamic product logic).

Hosted on a Liquid Web dedicated VPS.

Recently added Cloudflare (currently in “under attack” mode as a temporary fix).

Current Issues:

Website slowness and errors (max children processes, PHP/MySQL load).

Cloudflare showing “human verification” checks to normal visitors.

Possible conflicts in custom PHP functions creating large logs and server strain.

What We Need:

Audit & optimize server setup (PHP-FPM, MySQL queries, Apache/Nginx).

Debug custom WordPress code for clashes and unoptimized logic.

Configure Cloudflare for speed and security without human verification checks.

Deliver a fast, stable website without breaking custom functionality.

Requirements:

Strong PHP & WordPress (custom theme/functions).

Linux VPS admin experience (Liquid Web, Apache/Nginx, PHP-FPM).

Cloudflare setup & fine-tuning.

Proven experience solving performance issues at both server + code level.

Timeline: ASAP (urgent).
