Discover my design skillset

I specialise in turning complex problems into clear, intuitive digital experiences. My work blends research, UX strategy, and thoughtful UI craft — always with a focus on usability, clarity, and measurable impact. I design collaboratively, iterate quickly, and ground decisions in evidence rather than assumptions.

UX Research

I uncover user needs through interviews, card sorting, and collaborative workshops — turning insights into actionable design direction.

UX Design

I bring structure to complexity, designing flows and interactions that feel effortless while solving real user problems.

UI Design

I craft clean, modern interfaces that reflect brand personality and support usability — with a strong eye for detail and consistency.

Testing & Iteration

I validate designs through user testing and analytics, then refine them to improve performance and deliver stronger outcomes.

What people say

I’ve collaborated with incredible people over the years, and I’m grateful for everything we’ve built together. These are some of the reflections they’ve shared about our work.
“Kati did an excellent job as the lead product designer at Good-Loop. She has strong design skills, plus a great approach to collaboration. She organised and ran monthly design workshops that were genuinely collaborative and productive - then produced great designs from the varied inputs. In a similar way, the also brought client feedback into our design process. She's positive and open - someone who in a gentle way, helps build the team as well as the product. Highly recommended.”
Daniel Winterstein
Founder and CTO, Good-Loop
“Katalin is truly a talented Creative UI/UX Designer. Her ideas are remarkable, well balanced with paying attention to details. I had a pleasure to co-operate with her on various UI/UX design concept projects from the User Experience point of view. Her professionalism while doing surveys and interviews with me in User Preferences A/B Testing was on a very high level. Katalin UI/UX projects are well designed with pixel-perfect precision, beautiful colour palette, and user-friendly flow. I found her Mobile Apps and Websites useful and quite needed on the market. It was my pleasure to study with Katalin at Career Foundry at our UI/UX Design intensive remotely course. It will be very beneficial to have Katalin in UI/UX Designers Team due to her friendly, helpful and positive attitude. I wish you, Katalin a great success in your new UI/UX Design position.”

"I had the great pleasure of getting to know Kata when I accepted the CEO role at Actify. Kata's manager, the head of marketing, left the company for personal reasons around the same time that a marketing teammate of Kata's passed away unexpectedly. This put Kata in the position of taking on an extraordinary amount of additional responsibility, as well as having to bring me up to speed until we were able to make some adjustments. I was very impressed with Kata's talents as a marketer and especially as a designer, as well as her work ethic. Her contributions not only impressed me, but some outside assistance we brought in to conduct a positioning workshop and launch development. I was very much looking forward to her participation in a new product launch we were planning, and her decision to pursue her dream job left all of us at Actify sorry for our loss, and at the same time very happy for her opportunity. She has a place here at any time, and I can't recommend her work highly enough."
Dave Opsahl
CEO, Actify
“I was Katalin's Career Coach while she was a student at Career Foundry. From our first meeting it was clear that Katalin is determined to become an incredibly talented designer as well as an excellent colleague within an organisation. She has a strong attention for detail, worked through challenges quickly and was always keen for feedback on how to grow. In our coaching sessions she showed a high level of self-awareness. I would reccomend her to any organisation.”

“I've worked alongside Katalin for over two years. During that time, I've seen her excel in her role as a marketing professional. Kata quickly understood the complexities and functionality of our software applications and effectively supported the development of technical content and material.Kata’s creative skills went beyond the scope of her daily role, her contributions to company artwork enriched our internal and external communications. She actively contributed to the furthering of our software’s user experience through internal stakeholder feedback sessions.Kata adapted quickly as our small business was agile and rapidly growing. Her willingness to learn and take on new responsibilities is something to be desired in any professional. Kata’s competence with both creative and technical deliverables is a rare mix and made collaboration and brainstorming enjoyable and a fruitful exchange. Kata’s enthusiasm and kind nature means everyone loves working with her, no matter where they fall on the org chart.I recommend working with Kata. I wish her every success for the future.”
