About Me

Hey there! I'm Mari!

Product Designer focused on creating intuitive, inclusive, and scalable digital experiences. I combine research, prototyping, and systems thinking to design products that balance user needs, business goals, and technical constraints.

With HTML and CSS knowledge, I collaborate closely with engineering teams to ensure designs are implemented effectively, bridging the gap between design and development. Accessibility is central to my work, creating products that are intuitive and usable for all users, regardless of abilities or limitations.
