ABOUT × THE PERSON BETWEEN THE PIXELS

Designer by instinct.
Engineer by practice.
Experimenter by curiosity.

I'm Josue Somarribas, a UX Engineer and CRO Developer connecting human behavior, interface craft and production code.

8+ years across UX and web development · Based in Spain · Born in Costa Rica

I work in the overlap.

The most interesting product problems rarely belong to one discipline. I like following them across boundaries—from the first awkward question to the production details that decide whether an idea survives.

People, interfaces and systems overlap to create useful things that ship

A few things I believe

01

Clarity is a feature.

If people cannot understand it, the interface is not finished.

03

Flat results are still results.

Experiments are for learning, not decorating roadmaps with wins.

04

Details are where trust lives.

Spacing, performance, accessibility and copy all shape the experience.

Design foundations

Curiosity, structure and the basics that never stop mattering.

Web development

Turning designs into working interfaces. Learning the web.

Product & UX

Understanding users, problems and how products create value.

UX engineering

Bridging design and code. Building with performance in mind.

Experimentation & CRO

Testing assumptions. Learning from behavior, not opinions.

Now: building across the full loop

From question to ship to learning. And repeat.

What I bring to a team

See the problem

Research, synthesis, journey friction, hypothesis framing.

Shape the experience

Flows, interaction design, prototypes, design systems.

Make it real

Front-end, responsive behavior, accessibility, analytics and experiment QA.

OBSERVE → FRAME → PROTOTYPE → INSTRUMENT → SHIP → LEARN

UX does not stop at the screen.

Alongside digital products, I host travellers from around the world in Costa Rica. More than 70 guest reviews have taught me the same lesson as product work: comfort lives in anticipation, clear communication and the small details people should never have to ask for.
