Maria Tsioma

Product Designer

10 years of design experience across hospitality,

event technology, e-commerce, B2B, and SaaS.

I shape digital experiences that bring clarity to

complex systems and connect product strategy

I’m drawn to projects where structure, usability,

and thoughtful design come together to create

products that are clear, useful, and scalable.
