You talk directly to the project lead who owns the outcome — no account manager relaying your words to the people doing the work.

Vladyslav
Chystiakov
In development since 2015. Your task goes straight into the work — no account managers, no retelling through third parties: what you explained and what ends up in the code are the same thing. The project is not handed over to a different contractor midway, and the reply comes within two hours rather than the next day.

How we work
Audit & brief
We measure the current site: catalog size, speed, sitemap health, analytics.
Structure & design
Category tree, filter facets, mockups for home, category, product and checkout.
Build & launch
Markup, catalog, payments and shipping, integrations, analytics, an end-to-end order run.
Growth
Post-launch measurements, data-driven fixes, ads. By priority — not "everything at once".
