Kateryna Tolstykh
Lead UI/UX Designer · Web & Mobile App Design
Designing user-centered web and mobile products that make complex tasks feel simple — and help businesses turn better experiences into measurable value.
User-Centered Design Built Around Real Business Goals
Kateryna is a Lead UI/UX Designer with experience creating new digital products and redesigning existing ones across web and mobile platforms.
Her work starts before the first polished screen. She structures information, identifies user and business needs, maps flows, and turns complex requirements into interfaces people can understand without instruction. That foundation allows her to design products that feel clear, consistent, and purposeful rather than merely attractive.
Since joining Mettevo in June 2023, Kateryna has collaborated with cross-functional and international teams, worked directly with clients, and translated business problems into practical product requirements. She sees user-centered design and commercial performance as parts of the same task: a better experience should help users succeed and help the business grow.

Inside Web, Mobile & E-commerce Product Design
Kateryna designs digital products from early discovery through developer handoff. Her focus is the structural UX work that makes an interface intuitive, paired with the polished responsive UI needed for web platforms, mobile applications, e-commerce experiences, and high-impact website redesigns.
Web & Responsive Design
Designs clear, conversion-aware websites and responsive interfaces that remain consistent across desktop, tablet, and mobile. Information hierarchy, reusable patterns, and practical developer handoff are considered from the beginning.
Mobile App Design
Creates user flows, wireframes, prototypes, and production-ready interfaces for mobile applications. Designs around real usage contexts, platform behavior, and the limited space where every interaction has to earn its place.
E-commerce Web Design
Designs product discovery, category navigation, product pages, carts, and checkout flows with usability and conversion in mind. Removes friction without sacrificing brand character or visual clarity.
Website Redesign
Audits existing experiences, identifies structural and usability problems, and rebuilds them into clearer, faster-to-understand interfaces. Preserves what already works while improving navigation, hierarchy, responsiveness, and conversion paths.
Figma Design Systems
Builds scalable Figma libraries using auto layout, components, variants, styles, UI kits, and interactive prototypes. Creates systems that keep complex products consistent and make collaboration with development teams more efficient.
UX Research & Information Architecture
Uses research, personas, site maps, user flows, and business analysis to define what the product needs before deciding how it should look. Structures complex content and data so users can find, understand, and act on it.
Cross-Functional Product Collaboration
Works with clients, product stakeholders, developers, and international teams to clarify needs, form product requirements, and carry design decisions through implementation.
