UX / UI Designer · Investigate. Decide. Ship.
Alfonso
Barreiro
The gap between what a product does and what users actually need is where the design work lives. I frame it, map the trade-offs, and ship the simplest thing that closes it — sometimes by cutting features, not adding them.
Long-press to pin, pause, or remove. One surface, reversible.

About
Thirty years of building.
Still asking why it doesn't work better.
I wrote my first code at eight, typing BASIC line by line from a magazine into an Atari 800. I built my first website at 22, a Rush fan site that probably broke every design rule that existed. Thirty years later, I'm still doing the same thing: staring at something on a screen and asking why it doesn't work better.
I design from the gaps I actually live in. Spotify is my most-used app, and the Recently Played shelf had blind spots that bothered me for years. I dealt with plantar fasciitis, toenail fungus, and the quiet shame men carry about neglecting their own bodies, so I built a resource for it. Each project starts with a real problem I can feel, not a brief I was handed.
At 56, I still learn like I'm running out of time. I'm teaching myself Hiragana. I walk five miles a day, building back toward a marathon. I meditate. I watch birds. I read everything. If that sounds like someone with too many interests, you're probably right. But the curiosity is the same muscle I use in research. I just don't turn it off.

How I work
The problem comes first. Figma comes last. Research shapes the brief. The brief shapes the structure. The structure shapes the interface. The decisions that matter most happen before the first frame.
