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.
