It's me,
Mah-d-ßen.
Designing intentional experiences since ‘04
For me, great design happens where method meets instinct.
Hands-on at every step, I design, mentor, structure processes, and support bold ideas.
My journey has led me to design products for Fortune 500 companies, startups and indie entrepreneurs. The projects I worked on helped millions and have earned recognition from highly acclaimed media outlets around the globe.
On the day-to-day, you will often find me trying to keep a positive attitude and advocating for fairness.
I'm also known as:
- Founder of Frido & Friends
- Lead designer of Mecedes-Benz's Fuel & Pay feature
- The human behind the design & development of Brazil’s first Coca-Cola Facebook app
- Writer of a few eclectic articles
- Pro bono mentor
- The alter ego of Midnight Valley
- A hackathon enthusiast
- Source of inspiration for portfolio design among Brazilian designers
- An indirect Emmy award winner
