Improving mobile app onboaridng to get more paying customers?

I help boost onboarding experiences and implement the best practices for high-converting funnels to increase revenue, LTV, and other metrics.

Working on a new website and want to make it right?

Building new things is hard. What's harder is making it better than it was before. But fear not, there's a way to do it.

Need fresh professional eyes to streamline a complex SaaS?

SaaS is complex, but it doesn't have to be. I help create software that customers understand and love because it works seamlessly.

I'm Kirill, your UX and product partner

Over 15 years, I developed 2 superpowers that help improve digital UX.

Enhancing clarity
I help display information and actions simply and logically. Clear copy, easy navigation, and design principles help minimize cognitive load and guide users through their journey.
Simplifying complex
Adding "just one more button" today can quickly complicate an experience in the long run. I specialize in simplifying complex and confusing processes into straightforward user journeys.


A/B tests
I tested hundreds of UX hypotheses to learn what works, so you don’t need to.


User interviews
I spoke with lots of users to learn what good UX actually means, and how to achieve it.


Years of experience
I believe in the power of consistency and repetition when it comes to money.


Experiences improved
I improved more than a billion user experiences for people just like your customers.

Why teams love UX Boost

Improved conversion

A simple user experience translates into getting more people who buy from your business.

Streamlined experience

People find it easier when products work in the way they already know and understand. I use best practices to make it happen.

Actionable insights

Very specific suggestions to tackle very specific problems, nothing high-level or vague. Simple changes that make a significant difference for your customers

Fresh eyes

Constant exposure can lead to the 'curse of knowledge' bias. I bring a fresh perspective to illuminate overlooked issues.

Removed bottlenecks

Solving some problems yields much better results than solving the other ones. I help unblock user flows to make your users get what they need.

How it works


I ask a lot of questions just like your doctor would, to understand where you are today, your Point A. We talk about your current business challenges that translate into UX space. Together we define your desired UX transformation outcome, Point B.

Research & investigation

I conduct a comprehensive investigation and use your analytical data to highlight all UX issues. I learn insights from your team and and prioritize issues to tackle first to get to your desired outcome.

Personalized UX strategy roadmap

I create a tailored roadmap to fight the list of prioritized UX issues. Often these would be small targeted design changes — we don’t need to re-design the whole thing. It could also include getting more data, running a survey, etc — whatever we need to make an informed decision.

Execution & results

I will be there to help and support you in executing your strategy to make the transformation happen and bring you to Point B. We’ll see the first results and iterate for the best possible outcome.


You're in a good company

Over the last 15 years, I helped level up user experience and business metrics for dozens of products and services. From startups to international giants, from mobile to desktop, to custom devices. My approach is versatile, and effective across different domains and platforms.

Your first step to better UX and conversions is just one click away.
