In e-commerce, every second of loading time is a loss in conversion. If your store "lags" and the server crashes with higher traffic – you are losing money. I conduct comprehensive code, database, and server audits, eliminating bottlenecks.
Load Time
Under 1 second
Online stores "bloat" over time. Installing random plugins, lack of updates, heavy images, and code errors cause customers to flee to the competition, and Google lowers your positions in the search engine.
Google officially promotes fast pages (Core Web Vitals). Code optimization is the cheapest way to improve organic visibility.
Amazon calculated that every 100ms delay causes a 1% drop in sales. A fast store builds trust and encourages purchases.
Old PrestaShop versions, module vulnerabilities, and PHP errors are open doors for hackers. An audit allows detecting and patching holes before it's too late.
The problem of a slow store rarely lies in "large photos". More often it is slow SQL queries and lack of cache. I go deep into the code and server.
$ mysql-slow-query-log analyze
! Found query taking 4.5s (join on `ps_orders`)
$ optimizing table indexes...
✓ Query time reduced to 0.02s
$ service redis-server start
✓ Cache Hit Rate: 95%
Fewer scripts, faster loading.
I improve results in Google PageSpeed Insights. I make the site load instantly on phones, which is crucial for the modern customer.
Was your store made by several developers and no one knows how it works? I perform a code quality audit. I remove "spaghetti code", fix security holes, and prepare the system for further development.
Why is this important?
Bad code hinders the implementation of new features. Fixing technical debt makes future changes cheaper and faster.
Maintainability Index: A
I grant permissions to code and server. I create a store copy (Staging) to avoid working on a live organism.
You receive a document with a list of problems, their priority (Critical/Recommended), and repair time estimation.
After acceptance, I implement optimizations. We clean the database, install cache, fix code.
We compare "Before" and "After" results. We check loading times and Google PageSpeed scores.
Sometimes it is cheaper to build the system from scratch than patching the old one. Check my implementation offer.
No, because I perform all work first on a test copy (Staging environment). Only after testing changes do I implement them on the production store.
It depends on the initial state. Often it is possible to shorten loading time from 4-5 seconds to below 1 second (TTFB), which is a colossal difference for the user.
Yes. Basic audit includes checking PHP version, modules, and potential vulnerabilities (SQL Injection, XSS) in custom code.
I usually prepare the report within 2-3 business days of receiving access. The time to implement fixes depends on the number of detected errors.
