UX & Product Designer — Sunnyvale, CA Tarmiga / Independent Practice / 2017–Present

Behavior first, interface second.Design that shifts what people actually do.

A decade at the intersection of behavioral economics, systems thinking, and design. The screen is where that thinking lands, not where it starts.

I am based in the San Francisco Bay Area. If you are working on problems that run deeper than the interface, I would like to meet you.

Designer Specifications
Starting point
The humans and what they're doing. Every problem starts with an empathetic understanding of what people are actually doing inside a system, and why that makes sense to them even when it produces bad outcomes. The design (interface, platform, process, or otherwise) comes later.
Foundation
Behavioral economics + industrial engineering + six years teaching both to engineers + UX skills. They're not credentials, but a specific way of seeing: where friction lives, why systems fail, how complexity becomes legible, how business connects to actionable policy design.
Method
Diagnosis before design + systemic perspective The problem is almost never where it first appears. Workers who don't fill out forms are not careless. Users who don't follow the designated path are not dumb. My job is defining what the real problem is through research, and then redesigning the system so that it actually produces the desired outcomes.
Skills
Multidisciplinary collaboration. Full-cycle design from information architecture, to user testing, mixed with front-end elements, and a translation between business strategy, technical requirements, stakeholder alignment. I also bring a multicultural background (Latam & Spanish + US & English) that promotes original and adaptive solutions for broader audiences.
Output
Something sustainable over time. Not a fix for today. A product that does not need to be redesigned in six months because it was built for how people really behave, not an idealized version of them.
Selected Work
2025 Ref.01
Platform design

CyberSectory

Security engineers weren't failing to search. They were each doing their own curation work, because no structured, trusted place existed that was built for them. That gap drove every design decision.

Mobile web app

Casa

Every household management tool we tried modeled the home like a calendar. Our home doesn't run like a calendar, and that gap drove every design decision. Designed and shipped in one day using AI, from brief to working product in just 2 days.

Game design

Fonograpp

Memory games for elderly users are built around scores and difficulty. This one was built around a different question: what makes someone want to come back tomorrow?

Email service

Cinemail

Existing cinema platforms collapse two separate user moments into one cluttered experience. The format decision was not a technical choice. It was a behavioral one.
