Mahdi Mohrehchi

Senior Product Designer

I’m a product designer with over a decade of experience and a habit of building things to figure them out.

I like building things and I like building them well, even the ordinary ones. I care about how they work, why they work that way, and how they look.

Living somewhere on a big floating rock; to be exact, in Berlin.

About me

I’m a self-taught product designer, building digital products since 2015 for startups and bigger companies across SaaS, fintech, e-commerce, and tourism. It’s still a little crazy that I get to do this for a living.

Between 2020 and 2022, I co-founded Done Studio, a design and development studio. Running it taught me what it takes to ship a product beyond the design work.

While working as a designer, I studied software engineering, then switched to industrial design. Both still influence how I think about what I’m making and how people will use it.
