About

I design product details around the people who will use them.

An ICT engineer turned product designer, drawn to the human reasons behind product decisions, habits, and friction.

01

People First

I started out writing the code. Over time, I became more interested in the people on the other side of it: what they notice, where they hesitate, and what helps them move with confidence.

02

Behavior Curious

I have been hooked on behavioral psychology since childhood, when Tim Roth's microexpression expert got me asking why people do what they do. I bring that same curiosity into UX.

03

Access By Default

Being red-green colorblind means accessibility has always felt personal, not like a checklist. I care about interfaces that stay clear when real people, real contexts, and real constraints enter the room.

Now

Building the bridge between design judgment, prototypes, and AI-assisted workflows.

What I am sharpening

Product thinking, UX writing, interaction details, accessibility, and using code or AI tools to make design decisions easier to test.

What I am looking for

A junior product design or UX role where I can work close to real product problems, learn from senior designers, and keep building hands-on prototypes.

Where I add energy

Messy flows, unclear hierarchy, early concepts, usability friction, and the small details that help people feel less lost inside a product.

The bit I can't turn off

Some people scroll past the things that almost work. I usually can't. Interfaces, ad campaigns, onboarding flows, everyday interactions with one missing piece. At this point I have stopped trying to turn that part of my brain off.

I am direct, I ask a lot of questions, and I am a skeptical dreamer, which turns out to be a surprisingly functional combination.
