Elimination of load issues on WordPress/WooCommerce hosting site

We are looking for a specialist to diagnose and resolve issues with the load on the WordPress/WooCommerce hosting site.

There is an active e-commerce site on WordPress + WooCommerce. The site periodically crashes or works unstably during a high number of requests — from various IP addresses as well as possibly from one or several sources.

Cloudflare is connected, but the problem is not fully resolved.

Input data:

• CMS: WordPress + WooCommerce
• Hosting: Hosting Ukraine
• Region: Ukraine
• The site is active, so all work must be done very carefully, without risking sales and the stable operation of the store.

What needs to be done:

1. Conduct a full technical diagnosis of the site and hosting:

• check the server load, memory, CPU, database;
• identify plugins, themes, or scripts that may create critical load;
• check the code quality, possible errors, conflicts, unoptimized database queries;
• check the site for viruses, malicious code, backdoors, or suspicious files;
• analyze whether external requests, bots, attacks, or incorrect Cloudflare settings may cause the site to crash;
• evaluate current caching, security, and performance settings.

2. Prepare a clear action plan:

• describe the identified problems;
• explain what critically affects the operation of the site;
• propose a prioritized plan for resolving issues;
• specify separately which actions can be performed without risk and which require a backup, staging environment, or additional approval.

3. Resolve the identified issues:

• optimize the site, plugins, database, caching, and settings;
• remove or replace problematic elements;
• set up protection against excessive requests, bots, or suspicious activity;
• if necessary — adjust Cloudflare settings;
• check the stability of the site after making changes.
  
  

Important:
The site is an active online store, so all actions must be performed carefully: with backups, step by step, without abrupt changes in production, and without stopping the store's operation.

Please respond only if you are a specialist with real experience in similar tasks: WordPress/WooCommerce, high load, Cloudflare, security, server resource optimization, malware detection, and technical audit.

In your response, please briefly indicate:

• your experience with WooCommerce and load issues;
• whether you have worked with Cloudflare;
• how you would start the diagnosis;
• examples of similar tasks you have already solved;
• your approximate approach to work and order of actions;
• your budget.

A regular developer for site edits is not needed. A specialist is required who has experience diagnosing WordPress/WooCommerce site crashes due to load, bots, problematic plugins, database queries, Cloudflare, and possible site infections.
