Hello!
The task is clear — it is a classic comprehensive optimization of a custom high-load website focusing on TTFB, JS weight, and CLS.
I have experience with similar optimizations for custom PHP/JS projects, where the main issues were slow SQL queries, overloaded frontend, and lack of proper caching/critical rendering path. I usually work in stages: first the server level (OPcache, SQL, full-page cache, CDN), then the frontend (JS/CSS split, defer/async, critical CSS), and finally images and CLS.
A couple of clarifications before starting:
— what stack does the project use (PHP framework or pure PHP)?
— is there currently Redis/Memcached or just file caching?
…
After this, I will be able to assess the risks and work plan more accurately.

Hello, I worked on optimizing the performance of an online clothing store with 2.1 million products - improved Performance from 23 to 89, reduced LCP from 8.2s to 1.8s, and increased conversion by 34%.
I see that your TTFB is 5.4s - this is very critical! Are you currently using any server-level caching, and what is your current database architecture for the product catalog?
I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team! ⚡

978 28 0 Hello! I can take on the performance optimization of booratino.com.ua.
I have experience with performance optimization for custom-built websites: LCP, TTFB, FCP, TBT, CLS, caching, JS/CSS optimization, images, CDN, and post-deploy checks.
According to your specifications, I see the main priority is to reduce TTFB from 5.4s, as this significantly affects LCP/FCP. I would start with the server side: Full Page Cache, OPcache, slow SQL queries, CDN/Cloudflare, and Brotli/Gzip. After that, I would focus on JS, CSS, images, and CLS.
I will also definitely check critical scenarios after changes: cart, filters, search, checkout, mobile menu, GTM/pixel, and forms, to ensure that the optimization does not break functionality.
I am ready to first conduct an audit, identify the main bottlenecks, and then gradually bring the metrics to the target values.

3282 42 0 Good day, I reviewed the website, I looked at your checklist (the items that need to be completed), I can optimize everything.
I indicated an approximate cost because we still need to understand what exactly the implemented website is based on, as it seems to be a custom-built system; if so, it could be even more expensive.

310 Hello, I can take on performance optimization focusing on Core Web Vitals: LCP, FCP, TBT, and CLS, as well as quickly separate frontend issues from server causes of high TTFB. First, I will conduct an audit of key pages to determine what is causing the most drop — JS, CSS, images, third-party scripts, or server response. After that, I will make safe adjustments for the first screen, lazy loading, defer/async, Critical CSS, and layout stability, with checks on the cart, filters, search, and order processing after the changes.
-
1351 5 0 Good day.
I can take care of the optimization. From the description, the problem is not only on the front end but also on the server side — TTFB of 5+ seconds indicates either heavy SQL queries or a lack of proper caching.
I can:
* set up Full Page Cache / OPcache / Brotli / Cloudflare
* optimize SQL and PHP parts
* unload JS (defer/async, lazy, GTM/pixel/reCAPTCHA)
… * extract critical CSS
* optimize images for WebP/AVIF
* bring CLS/TBT/LCP to reasonable values without "breaking the site"
After the changes, I will definitely check the cart, filters, forms, mobile, and analytics.
The estimated cost is $200–400 depending on how complex the custom code is and the state of the server.
Message me privately, I will look at the site and Lighthouse/server — I will honestly tell you what can realistically be achieved in terms of PageSpeed.

255 2 0 Hello!
I quickly looked at the site — there are 3 critical points that I can fix in a day, which will significantly improve PSI:
1. Cache-Control: no-store, no-cache — the browser forces a reload of all resources on every transition. This is the top issue, causing a ~3-5 second loss on repeat visits.
2. 239 images on the homepage without lazy-loading + not WebP. I will convert → loading="lazy" + WebP/AVIF with a fallback → -60-80% size reduction.
3. HTML 2 MB + 5 CSS files without bundling + GTM/VK/instafeed loading synchronously — render-blocking. Bundle CSS + defer/async JS = LCP ↓ by 1-2 seconds.
In 1 day I will do:
- Lighthouse audit (5 key pages)
… - All 3 points above
- Cloudflare/nginx tuning (gzip/brotli, asset cache headers)
- Critical CSS inline, font-display:swap, preload-hints
Please provide FTP/SSH access and admin panel — I will start immediately.

716 4 0 I will perform this task better than anyone else because I have deep experience with custom PHP projects, server-side optimization, caching configuration, and working with Core Web Vitals. My methodology is based on a step-by-step audit, precise measurement, and prioritization of changes based on their impact on speed. I do not just "speed up the site" — I build a stable architecture where every byte of code, every database request, and every image works towards the result. You will receive guaranteed improvements in metrics, preservation of cart functionality, filters, and forms, as well as detailed documentation of changes. My code is always clean, and my approach is transparent: you see progress after each stage.
Work plan:
Audit of the current state: measuring metrics in Lighthouse without cache, analyzing database requests, identifying bottlenecks in the server and frontend.
Server optimization: enabling Full Page Cache, PHP OPcache, configuring Brotli, connecting Cloudflare/CDN, refactoring slow SQL queries.
Working with JavaScript: adding defer/async, deferring GTM/FB Pixel/reCAPTCHA, removing unused code, lazy-loading for modules.
CSS optimization: extracting Critical CSS, minification, removing dead styles, inlining critical rules.
Working with images: converting to WebP/AVIF, preloading for LCP elements, lazy-loading, adding width/height to prevent CLS.
Final testing: checking the cart, filters, search, forms, mobile menu, and integrations after each deployment.
… Result control: final measurement in PageSpeed Insights and Lighthouse with mobile throttling, correcting remaining issues.

466 7 0 Good afternoon. The problem may not only be in the frontend (images, scripts, the layout itself), but also in basic database queries. For example, the absence of indexes can significantly affect performance.
I suggest the following:
You give me access to the code and the database, I will take a look and try to improve something - add indexes, optimize queries on a specific page, and see what is causing the slowdown. I will do this locally on my end, your site will not be affected, and I will make a backup beforehand. This will be done within a day (24 hours from the moment I receive access).
If there is any positive outcome - I will show you the difference, we will agree on the price (starting from 2000 UAH) and the timeline (starting from 2 days) and make a decision about further cooperation.
If not - no one owes anything to anyone, you continue your search, and I will too.

1460 5 0 1 Hello. I have thoroughly studied the technical specifications and the PageSpeed screenshots of your website. The task is interesting, but the main difficulty lies in the fact that it is a custom engine, so standard solutions will not work here, and I will have to work directly with the core and the database. A server response time of more than five seconds indicates a bottleneck in the database architecture or a lack of hosting resources, so first of all, I will start with profiling the queries and setting up aggressive server-side caching. Next, I will manually rewrite the logic for loading scripts and styles to eliminate render-blocking and configure the generation of modern image formats. After each stage, I will conduct manual testing of the cart and filters to ensure stable functionality. Such deep optimization will take about a week. Please let me know if you currently have access to the server control panel or SSH, and what version of PHP is currently being used in your project?

296 1 0 Hello!
Working with custom engines is always a challenge that I enjoy. You can't just "install a plugin"; you need to understand the logic of the developer who created the system. I specialize in optimizing high-load projects and guarantee bringing PageSpeed metrics into the "green zone".
My technical optimization plan:
Backend & Database:
Query analysis: I will conduct a review of SQL queries. A common problem for custom sites is the lack of indexes in the database or cyclical queries that "crash" TTFB (time to first byte).
… Server-level caching: I will implement Redis or file caching for parts of pages that rarely change (menu, footer, product specifications).
Environment update: I will check compatibility with PHP 8.1/8.2 for an instant speed boost.
Frontend & Rendering:
Critical CSS: I will extract styles for the first screen and load them inline so that the user sees content instantly.
JS/CSS optimization: Minification and merging of files. Moving non-critical scripts (metrics, chats) to defer or async.
Fonts: Local loading using font-display: swap to eliminate text jumps.
Working with images:
Implementing automatic conversion to WebP at the server level.
Setting up proper Lazy Load for the product grid.

6589 28 0 The task is clear: to raise the Performance from 27 to 75+ on mobile through server caching, OPcache, defer/async for JS, Critical CSS, WebP + preload for LCP images, and connecting Cloudflare.
I will complete the full cycle across all 4 blocks of the technical specifications, checking the cart, filters, forms, and GTM after each deployment. I will document the results with screenshots of PageSpeed before/after.
The budget is 2000 — I am ready to discuss, depending on access: is there SSH to the server or only FTP + hosting panel?
