Marcio Barrios
Design Engineer
I move pixels. I shape ideas. I sweat details. I make it click. I build for humans.
I turn ideas into interfaces that feel good to use.
Somewhere between design and code is my happy place.
Currently a Product Engineer at MITO AI (opens in a new tab), building tools for filmmakers. Previously, I helped shape the web at Sketch (opens in a new tab).
Outside the canvas: family, a game of padel, or backpacking with the kids in tow. Always taking photos, still playing football on Sundays.
I like making things. And going places.

Good things happen in the details.
Thanks for noticing a few of mine.
