Hello, I’m a problem-solving product design leader with 8+ years of experience.

I’ve had the privilege of working with Kadu as my manager in the last three years. His leadership style puts the team first, creating an environment where collaboration and growth are prioritised, while also giving space for individual contributors to grow and own their projects.

He is not only a strong people manager but also a hands-on design leader. His attention to detail, and his expertise in building and maintaining design systems has been invaluable in driving consistency and scalability across our products.

I had some managers, but Kadu is one of the most complete. He's a great people oriented, create a creative space for his team and a hands on designer that also contributes on the projects. Co-working with him has been a constant learning opportunity — he balances management responsibilities with design craft, leading by example and supporting the team with business and product strategy. I hope we can cross our paths in the future.

I have had the pleasure of working with Kadu over the last few years, and I can say without hesitation that he is one of the best designers that I have ever worked with. Kadu has a keen eye for detail, behaviour and user experience.

What really sets Kadu apart is his leadership. He doesn't just design he mentors, elevates and inspires others around him. I've witnessed first hand the appreciation that people speak to Kadus' mentorship.

Any team would be fortunate to have Kadu bring his creativity, professionalism and deep passion for design to everything he does.

Kadu is extremely creative, dedicated and competent. It is always looking for the best solutions to solve challenges with imagination and intelligence. It is versatile and works in several areas with safety and competence. He is friendly, positive and calm. It conveys its vision clearly and looks at other perspectives openly.

So working in a team with him is easy, effective and very, very pleasant.

Creative, versatile and above all competent, Kadu has an excellent team spirit. It was a pleasure to share ideas, knowledge and the working space during the time we worked together.

Kadu is a professional who combines a lot of experience with an integrated view of the entire business: from the client to the consumer, passing through the “filling” developed by the agency. Working under his supervision was very productive.

Kadu is a hands-on leader, deeply involved with the team and actively contributing to day-to-day execution. He is approachable and supportive, providing constructive feedback that strengthens collaboration within the team. I truly valued our project sessions, where he consistently emphasized design consistency and strongly advocated for the best user experience. It has been a real pleasure working with him!

Kadu is a very capable professional, as well as an awesome person to work with. Beyond his creativity and technical ability by itself, this is very important to know how (and when) to clearly communicate and “sell” your ideas, work as a team, and deal with different points of view. Kadu has all these skills and has definitely improved our product value through his insights and implementations.

We had a great challenge creating a unified view of our newborn product, refining product vision, and identity, managing different stakeholders’ expectations and helping our Product Owner to provide the dev team with a clearer view of what needed to be done. Even after he left the team, his work keeps making difference here.

I had the pleasure to work with Kadu Szili at keezag. Unfortunately, it was just for a very short period. Nonetheless, it was long enough to be very impressed with his professionalism.

Starting with collaboration, where he showed an open mind to truly listen and understand the feedback provided by other teams such as product, tech, marketing, and sales. He also brought structure to the team by bringing in a more effective way of working, where feedback was collected and approvals were made throughout the process, in order to make sure we were all aligned by the time the work was completed.

I do not hesitate to refer Carlos Szili for a UX role in any Tech company and will be more than happy to work with him again in the future.

Versatile, dedicated, creative and affable. Kadu is undoubtedly an added value to a team and works tirelessly for quality and to ensure that all work is done on time and with quality.

I’ve had the pleasure of working closely with Kadu as my Lead Product Designer, and he is truly an exceptional design leader. Kadu is not only a great communicator and collaborator but also an outstanding problem-solver. He constantly encourages his team to explore different solutions and possibilities, always keeping user experience at the center while ensuring the delivery of valuable features for the business.

What sets Kadu apart is his combination of design expertise and technical knowledge. He stays up to date with the latest technologies and applies that awareness to elevate both design quality and execution. His holistic understanding of our entire product ecosystem—how each product connects with others from both a user and business perspective—has been instrumental in driving alignment and impact across the company.

Kadu has led multiple B2B initiatives, new product launches, and played a key role in establishing our design library and implementing the design system. His leadership has not only strengthened the team but also created long-term value by improving consistency and scalability in our design practice.

Any organization would be lucky to have Kadu leading their design efforts—he brings vision, structure, and a passion for creating outstanding user experiences.

Kadu is one of the most creative user experience designers I have worked with in Digital Commerce Platform of Mercedes-Benz. He doesn’t only thinks of customer experience with the UX components but also keeps the development team and the availability of data in mind.

He does good piece of research before finalizing any customer journey and experience and is trying to design as much generic components as possible keeping resusablity at hands.

I wish Kadu a good luck and wish we could work together again.

Kadu is an extremely committed, focused and intelligent professional. He has excellent interpersonal relationships and manages problems and conflicts very well. Highly professional and an excellent co-worker. Highly recommended.

Kadu was, without a doubt, one of the best business partners I’ve had in these 10 years with the company. He always put the company’s interests first and knew how to perform his tasks with excellence. Self-motivated, punctual and highly qualified professional. Whoever hires him will be lucky!
