Senior Product Engineer · CDMX / Remote

Form follows people.

I build interfaces that make sense to the people using them. Seven years shipping fintech and automotive products, with an anthropologist's eye for how things are really used.

03 · Concept · Unofficial · 2026

Activating a phone line on a low-end device

A redesign concept for a mass-market carrier's activation flow: slow networks, small screens, first-time users. Not affiliated with the brand.

In progress

Numbers say how much. People say why.

I studied social anthropology before I wrote a line of code. I still work like a fieldworker: it is how I find the problem behind the metric.

Observe

Interviews, field visits and behavior data, before deciding what to build.

Decide

A clear hypothesis, a metric, and an architecture that still holds in a year.

Measure

Accessible by default, tracked from day one, revised with what data and people say.
