This portfolio showcases my recent work (2020 - 2025) in the area of user experience design. For a selected pieces of my work created between 2007 and 2020 in the domains of graphic and web design, please refer to my older portfolio available at portfolio.matusiak.info.
Having worked with Bart for approximately 3 years, I have seen his commitment to his craft first hand. He truly wants the user to be represented and well taken care of and he has the skills to make sure the team is aware of what it will take to have that happen. Through mockups of varying fidelity, usability studies, user flow diagrams, and presenting all of the above to our internal customer - Bart showed tremendous professionalism at every turn. — David, Vice President
Bart designs consistent and focused experiences and does so while being an excellent teammate. He consistently provides great design enhancements for our software that would facilitate a better flowing, more consistent user experience. His knowledge and experience goes far beyond his primary interest of user experience. — Anass, Director, Information Services
Bart is a fantastic UX designer and goes well beyond aesthetics. He was integral in helping introduce the atomic design pattern at Alata and facilitating design reviews so that we could build UIs like Lego blocks that really favored composition. — Grahame, Software Development Manager
Bart has a natural gift for design, user experience and client workflows. He is also an excellent team player, quickly shifting focus from one project to another. He shows initiative in building out our UI/UX architecture from scratch, but he also played a massive role in pushing our product forward from a design perspective. — Reena, Software Development Manager
I've had the pleasure of working with Bart on several software development projects, and his UI/UX design work is always top-notch. He has a keen eye for detail and consistently delivers clean, user-friendly designs that elevate the entire software product. He is a true asset for any team. — Andres, Data Analytics Manager
Bart is an incredibly hard worker with a passion for quality. He has great ideas, does great work, and is also a fun person to have on your team. I worked with Bart for over 6 years and genuinely enjoyed our time working together. He cares deeply about user experience and is great at bringing his knowledge and expertise into conversations about new features. Bart works well on his own and also in collaboration with his coworkers, and he will make a fantastic asset to any team he is on. — Kelsey, Software Developer
