As COO, I worked closely with Iurii, who led our IT department with rare clarity and ownership. He consistently turned business needs into reliable technical solutions, improved our infrastructure, and kept delivery predictable even under pressure. Communication was straightforward, priorities were transparent, and results were measurable. I'd gladly work with him again and strongly recommend him.

I have worked together with Iurii Rogulia in company Suomen Pehmeä Ikkuna Oy, where he conducted IT development and support. Thanks to his expertise, all tasks were solved in time. It's clear from the sales statistics the moment when Iurii finished and launched new webshop. That led to double sales. I personally recommend Iurii as professional expert in IT development sphere.

As Head of Production I had the opportunity to work closely with Iurii during his time with our company. Although I do not have a technical background, it was clear to me that he is a highly competent and professional IT specialist. He approaches his work in a structured and well-documented manner, ensuring long-term stability rather than quick fixes. I particularly value his ability to fully understand business needs before implementing solutions, as well as his responsiveness in urgent situations. His contribution extended beyond his formal responsibilities, often bringing valuable insights to the team. I confidently recommend Iurii for any technical role.

Our previous SEO agency sent us a 60-page PDF every quarter, none of which our developers could actually act on. Iurii's audit was the opposite — short, technical, written for the people who would fix it. He found malformed Product schema across our entire catalogue, missing BreadcrumbList, and a Review snippet our team had built that Google was silently rejecting. Rich results appeared in search within three weeks of implementation. Worth every euro.

We had three CRM options on the table and kept going in circles for weeks. Sent Iurii our list of needs, he came back the next day with a clear pick and a short explanation why the other two wouldn't work for us. Done.

Iurii built our entire B2B platform from scratch in a remarkably short time — a fully multilingual webshop covering 32 European markets in 28 languages, with automated VAT calculation, VIES validation, Stripe payments across 6 methods including SEPA and bank transfers, server-generated PDF invoices, and Notion as our CRM. Everything was integrated and working end-to-end, not just a prototype. As someone responsible for both sales and operations, I especially valued that he understood the business side — compliance requirements, B2B buyer expectations, different payment preferences across markets. He asked the right questions upfront, kept things transparent throughout, and delivered without dragging it out. Highly recommend.

We were about to hand a project off to a new development team and I wanted someone to look at the code first. Iurii reviewed it and found a few things that would have caused real problems down the line. The new team thanked us for the cleanup.

We were ranking in Dutch but completely invisible in Belgium and Germany — same products, same pages, just translated. Iurii's audit found three things in 48 hours: hreflang tags pointing at the wrong canonicals, a sitemap that listed only the Dutch URLs, and product schema that didn't carry over to localized pages. The report was specific enough that our dev team fixed all of it in a week. Traffic from non-Dutch markets doubled the next month.
