Emmanuel Martinez

Engineer. I like programming, dev tooling and good interfaces.

Currently at Infobae, building Scribnews.

Most of my day is code; the part I care about most is how things feel once they're in someone's hands.

I'm not a designer, and I'd rather say it than fake it. I use AI to close that gap: I bring the reference and the taste I'm still developing, agents help me measure, spec and build. This site is where I keep what that process actually looks like, mistakes included.

Components

Small pieces built in isolation, every state at a time. Live previews, not screenshots.

AI for UI

Long-form notes on building interfaces with agents when you're not a designer. Each one follows the same path: reference, spec, build, what broke, result.
