"I had the pleasure of working with Jo at ZIEL AG. Jo designed the mobile app and I built it in React Native, so I was usually the first person to open a new design and start asking questions.

Jo has a clear vision for a product. Not just what a screen should look like, but where the whole thing is going and how someone moves through it. In our planning sessions she often sketched something in a few minutes and the rest of us finally understood what we were building. That saved us from a lot of wrong turns.

The designs were beautiful, but never only that. Jo cares about type, spacing and motion, and the app looked far more polished than you'd expect from a team our size. She also understood how mobile works, knew what's native on iOS and Android, and didn't hand over anything that looked great in Figma but would take a week to build. If something turned out to be tricky, a quick call was usually enough to agree on a version that worked for both of us.

Her work didn't stop at the handoff either. Jo tested the builds herself, went through the flows on a real device and told us when something felt off, not just when it looked wrong. A lot of small things that would have annoyed users got caught because she took the time to check.

On top of that she taught herself web design and built our funnels and marketing flows. Nobody asked her to. We needed it, so she learned it and shipped it.

Jo is also just nice to work with. Open to feedback, not precious about her work, and always thinking about the person using the app.

I'd happily work with Jo again, and I'd recommend her to any team building a product."

"I've had the pleasure of working with Jo at ZIEL AG, where she has been a key driver of product design and growth for our app, Zack. What stands out most is how much she owns: she moves easily between UX/UI design, content creation, growth marketing, CRO, ASO, and go-to-market strategy, effectively running the product and growth function on her own.

Jo has a rare ability to diagnose problems at the root rather than treating symptoms, and she pairs that analytical thinking with strong design instincts and follow-through. She brings a level of ownership and craft to her work that I've come to rely on, and she approaches challenges with the mindset of a product strategist.

I recommend her without hesitation."

"I had the pleasure of working with Jo on an advanced agentic chat app where she led the development of a custom design system.

Jo showed particular skill in translating complex AI interactions into an intuitive user interface while maintaining consistency across our design system.

It was great to work with someone who always tried to understand the problem and was always aware that we're working on our shared goal of delivering a successful project."

"Working with Jo has been an exceptional experience characterised by an outstanding work ethic, clear communication, and remarkable design skills.

Jo consistently delivered top-quality work, going the extra mile to ensure our project's success. Jo's proactive approach, coupled with the ability to connect us with other talented consultants, resulted in a comprehensive brand revamp that exceeded our expectations.

I highly recommend Jo for her professionalism, dedication, and remarkable design expertise."

"Collaborating with Jo has been a fantastic experience. Jo not only creates visually stunning and user-friendly designs but also ensures they are well-structured and developer-friendly.

Every detail is thoughtfully considered, making the implementation process smooth and efficient. Jo's ability to communicate clearly with developers sets them apart - anticipating potential challenges, providing precise documentation, and always being open to collaboration.

Great professionalism and dedication make working together effortless. I highly recommend Jo to any team looking for a UX/UI designer who truly understands both design and development needs."

"Jo is a person who is extremely easy and pleasant to work with. Her enthusiasm and openness to other people, combined with the experience of an educator, are essential features of an effective UX/UI designer.

She is full of great ideas, and quickly learns and implements new techniques and solutions. It's not often you meet someone so open-minded, talented, hard-working, and humble at the same time.

Her passion, constantly setting new goals and personal growth are impressive."

"Jo helped us refresh our website and give it a more professional look. She was a pleasure to work with, helping us think through our needs and suggesting changes to better reflect our goals and match our technical abilities so that we can maintain the site ourselves in the future. We highly recommend Jo and would welcome the opportunity to work together again."
