We are looking for an experienced specialist in performance optimization of WordPress / WooCommerce sites.

❗ Important: we need a not just a plugin configurator, but a developer with an understanding of optimization at the code and server infrastructure level.

In short: we need a person who actually speeds up websites, not "just installs WP Rocket and leaves".

Project Goal

To bring the site to the green zone in PageSpeed Insights.

At the same time:

• ❗ Without breaking functionality

• ❗ Without "inflating" metrics (artificial hacks)

• ❗ With real acceleration of page loading

What Needs to Be Done

1. Audit and Analysis

• Analysis of current performance (PSI, Lighthouse, WebPageTest)

• Identification of bottlenecks (TTFB, LCP, CLS, JS blocking, etc.)

• Checking server metrics

2. Frontend and Code Optimization

👉 Important: work through code (functions.php, hooks, dequeue, etc.), not just plugins

3. Image and Media Optimization

• Conversion to WebP / AVIF

• Setting up responsive images

• Lazy loading

• Control of image weight

4. Server Optimization

• Setting up caching:

  • Redis (object cache)

  • Varnish / Nginx FastCGI cache

• Optimizing TTFB

• Checking PHP / MySQL configuration

• Working with CDN (if needed)

5. WooCommerce Specifics

• Optimizing cart / checkout

• Reducing load from WC scripts

• Working with AJAX and fragments

• Exclusions from cache where necessary

6. Final Check

• Checking all site functionality after optimization:

  • cart

  • checkout

  • forms

  • user scenarios

• Staging check before deployment

Result Criteria

• PageSpeed — green zone

• Improvement of Core Web Vitals (LCP, CLS, INP)

• Real loading acceleration (not just numbers)

• The site works stably, without bugs

Candidate Requirements

• Experience in optimizing WooCommerce projects

• Experience with server caching (Redis, Varnish)

• Ability to read and optimize code (PHP / JS / CSS)

• Understanding of Core Web Vitals
  
  

Will Be a Plus

• Experience working with Cloudways

• Experience with high-load WooCommerce

• Cases "before / after" with real results

In the response, be sure to include:

1. Examples of actually accelerated websites (before/after)

2. What tools you use

3. Briefly — how you will approach the task

4. Experience working with Redis / Varnish
