Professional website optimization and acceleration

50% discount for the first 3 clients.

Is your website slow, pages take several seconds to load, your catalog is lagging, and your server is constantly overloaded?

I perform technical website optimization at the level ofPHP, database, SQL queries, modules, and server configuration.

What am I checking?
PHP:
  • Slow sections of PHP code;
  • Loading controllers and models;
  • Third-party modules and their impact on performance;
  • Repetitive and redundant operations;
  • Problems that arise with a large directory.
MySQL:
  • Slow SQL queries;
  • Missing or incorrect use of indexes;
  • JOIN, sorting, and filtering large selections;
  • Excessive database calls;
  • Queries that begin to "sag" as the number of products increases.
OpenCart:
  • Catalog and categories;
  • Cards Products;
  • Search;
  • Filters;
  • Cart and Checkout;
  • Import and Bulk Update of Products;
  • Third-Party Extensions.
Server:
  • CPU Load and RAM;
  • PHP-FPM;
  • MySQL;
  • caching;
  • web server configuration;

How is it going?

1. Diagnostics

First, I determine where the delay is coming from: PHP, the database, a specific module, the server, or a combination of several factors.
2. Finding the Root
I analyze real queries and application execution, rather than relying solely on PageSpeed metrics.
3. Optimization
I fix any identified bottlenecks: SQL queries, indexes, PHP code, configuration, or problematic modules.
4. Checking the results
I compare the metrics before and after the changes and verify that the optimization hasn't disrupted the catalog, shopping cart, search, or checkout experience.

What's needed for my work
For a full diagnosis and modification, you'll needFTP access to the site.

Depending on the nature of the problem, you may also needaccess to the hosting/VPS control panel—for example, to analyze server load, PHP-FPM, MySQL, logs, and environment settings.
Access can be grantedtemporary or with limited rights. After the work is completed, they can be disabled or modified.

It's important to emphasize to the client that PageSpeed metrics are not the determining criterion for optimization.[/i]
[i]Sometimes it's impossible to achieve high PageSpeed metrics without completely redesigning the site and layout, so this is only a tool that can simplify the solution to certain problems.[/i]

This is especially relevant if
— the store has significantly slowed down after catalog growth;
— the site has tens or hundreds of thousands of products;
— Search and filters are slow;
— The admin panel is slow;
— MySQL is resource-intensive;
—The server is constantly overloaded;
— After installing several modules, the site's performance has noticeably deteriorated;
— Standard caching methods are no longer helping.

My goal is not just to make the page "faster according to the test," but to eliminate the technical cause of the problem.

If you don't know what exactly is slowing you down, that's not a problem. You can start with a basic diagnosis.
