Hear from my employers

“We worked with Kirill at CRO agency ConversionRate.Store, where he most recently served as a Senior UX/UI Specialist. At our CRO agency, where we focus on optimizing thriving businesses to boost their key revenue metrics, crafting optimal UX/UI solutions for our CRO hypotheses is vital to winning A/B tests. A strong data-driven CRO hypothesis paired with a weak UX/UI solution is likely to fail, making UX/UI design a critical factor in the success of CRO experiments.

Kirill has an impressive skill set, consistently delivering UX/UI variations that strengthen CRO hypotheses and drive results for our clients.With our agency's A/B test win rate currently at 52%, Kirill’s creative and strategic approach to UX/UI design has been a significant factor in achieving this success.”

Ihor Sokolov

Co-founder & CEO at ConversionRate.Store

“It has been an absolute pleasure collaborating with Kyrylo over the past year. As a UI/UX designer, Kyrylo consistently impressed me with his ability to balance aesthetics with functionality, creating designs that not only look stunning but also drive measurable results.

In my role as a CRO consultant and Head of Operations, I’ve witnessed firsthand Kyrylo’s deep understanding of user behavior and his knack for transforming complex ideas into intuitive, user-friendly interfaces. His meticulous attention to detail, responsiveness, and ability to adapt to feedback set him apart as a true professional.

Kyrylo’s contributions have been instrumental in optimizing user experiences, leading to significant improvements in engagement and conversion rates. Beyond his technical skills, he brings a collaborative and solution-oriented mindset that makes working with him seamless and enjoyable.

I wholeheartedly recommend Kyrylo to any team or project that values exceptional design and user experience expertise. He is truly a game-changer in his field.”

About me

How to convey a brand’s emotion? How to tell a product’s story and build trust? How to make an interface simple and friendly? Why does a user leave before finishig the fu? I know the answers to these and many other questions. You can see this reflected in my work.I’m a Product Designer (UI/UX) focused on product growth. I design based on data, analytics, and user research, while still caring about clean and thoughtful UI. I’ve worked on websites and apps of different scales, from startups to large, complex AAA products, and have strong experience building and improving design systems.

Over the years, I’ve worked on AAA-level digital products across SaaS, e-commerce, and entertainment. These projects taught me how to balance functionality and emotion, connect design with real business goals, and deliver experiences that users enjoy returning to. My background in game UI helps me apply principles of motivation and engagement through light gamification, while modern AI tools make my workflow faster, more efficient, and insight-driven.Great design focuses on performance. It clarifies value, builds trust, and supports business goals.

Hear from my employers

“We worked with Kirill at CRO agency ConversionRate.Store, where he most recently served as a Senior UX/UI Specialist. At our CRO agency, where we focus on optimizing thriving businesses to boost their key revenue metrics, crafting optimal UX/UI solutions for our CRO hypotheses is vital to winning A/B tests. A strong data-driven CRO hypothesis paired with a weak UX/UI solution is likely to fail, making UX/UI design a critical factor in the success of CRO experiments.

Kirill has an impressive skill set, consistently delivering UX/UI variations that strengthen CRO hypotheses and drive results for our clients.With our agency's A/B test win rate currently at 52%, Kirill’s creative and strategic approach to UX/UI design has been a significant factor in achieving this success.”

Ihor Sokolov

Co-founder & CEO at ConversionRate.Store

“It has been an absolute pleasure collaborating with Kyrylo over the past year. As a UI/UX designer, Kyrylo consistently impressed me with his ability to balance aesthetics with functionality, creating designs that not only look stunning but also drive measurable results.

In my role as a CRO consultant and Head of Operations, I’ve witnessed firsthand Kyrylo’s deep understanding of user behavior and his knack for transforming complex ideas into intuitive, user-friendly interfaces. His meticulous attention to detail, responsiveness, and ability to adapt to feedback set him apart as a true professional.

Kyrylo’s contributions have been instrumental in optimizing user experiences, leading to significant improvements in engagement and conversion rates. Beyond his technical skills, he brings a collaborative and solution-oriented mindset that makes working with him seamless and enjoyable.

I wholeheartedly recommend Kyrylo to any team or project that values exceptional design and user experience expertise. He is truly a game-changer in his field.”

"Kirill is an amazing specialist with a very interesting vision. It was a sincere pleasure working with him.We asked him to work on a very specific project, which is quite difficult for most of the web designers. But his approach is outstanding!

A highly professional designer with a creative mind set and great approach to what he does. We will definitely continue working with Kirill on other projects and I highly recommend him to any other person, who is looking for a truly unique design!"
