Why clients trust me

I know the platform inside out

For over 5 years I worked on the CS-Cart team as a senior client-facing specialist: refining stores, contributing to marketplace development, writing add-ons, implementing integrations, and helping streamline business processes.

I understand common store pain points

Slow site performance, shipping issues, module conflicts, errors after updates, heavy SQL queries, outdated search — these are usually not unique cases but familiar problems for which proven solutions already exist.

I build maintainable solutions

No core hacks or quick fixes. Improvements should solve the problem now and survive future updates without unnecessary pain.

I speak business, not just code

I analyze the process first, then the code. What needs to change, who will be affected, where the risks are, and how orders, catalog, payments, shipping, and the admin will be impacted.

Client Testimonials

We've been working together for more than a year and a half, and I've never regretted it. Tasks are completed on time, the code is clean, without crutches. The developer knows CS-Cart well: add-ons, integrations, templates, optimization are all within his competence. He noticed problems in my TK several times and suggested better solutions. Always in touch, explains clearly.

Konstantin Borovikov

Product Manager at CNCMagazine
Working with Anton has been an absolute game-changer for our CS-Cart store! I am beyond thrilled with the results. He didn’t just fix bugs; he completely transformed our site’s performance. It’s rare to find a developer with such passion and precision. If you’re looking for a CS-Cart genius, Anton is your man. Simply incredible!

Luca

Founder of JengoLive
We were asked to expand the standard CS-Cart analytics — it was necessary to track the target actions of users and record them in the built-in CS-Cart analytical dashboard.

As a result, a separate module was implemented that collects the necessary data without affecting performance. We gained a deeper understanding of customer behavior and were able to adjust the sales funnel.

Maria

Product manager at Algorithm.Market
I approached them for some improvements, but it quickly became clear that the project had built up a lot of technical issues from the previous team. I’m not a developer myself, so it was really important that the specialist explained everything in simple terms and laid out a clear plan of action.

We did a full audit, pinpointed the weak spots, and suggested ways to optimize the site. After the redesign, everything became much more stable — the random errors disappeared, and planning further development became easier. I also really appreciated the transparency — all issues and solutions were explained clearly, without any unnecessary technical jargon.
