About Rafael Medina

About me

Hi, I’m Rafael.

I’ve spent the last ten years designing products, mostly the complicated parts people prefer not to think about. I figure out what to build, test it with real people, and stay for the fixes after launch.

I prototype in code. A working interaction answers questions faster than a static mockup, and usually faster than a meeting.

When I’m not working, I’m probably kickboxing, swimming, riding a bike, or being humbled by salsa and jiu jitsu.

  • Kickboxing
  • Mountain biking
  • Lap swimming
  • Hiking
  • Salsa (learning)

Now
Freelance, splitting time between Punta Cana and NYC.
