Product Designer & Builder
Hey!
I'm María, a product designer and builder based in Berlin, currently running product end-to-end at ToysReloved.
I dig into data and talk to users to find where the funnel leaks, decide what's worth fixing first, then design, test, and ship it myself, and measure whether it moved the needle. I use AI and automation to run the whole loop, so the team can focus on what matters.

HOW I WORK
HOW I WORK
01
Research & discovery
I start with the problem, not the aesthetic. Customer interviews, competitive analysis, and the data already sitting in the team's tools set the direction before a single screen gets drawn.

02
Decide & prioritize
Not every problem is worth solving. I turn findings into clear hypotheses, weigh impact against effort, and pick the few that will actually move the business. Saying no is part of the job.

03
Design & prototype
I design with data at hand and AI as a working partner, moving from wireframe to high-fidelity fast without skipping the thinking. Every screen earns its place by solving something specific.

Ship & measure
I own execution end-to-end, working directly with engineering to ship, then track what actually moved: conversion, checkouts, revenue. If it didn't move the number, it wasn't done.

Systemize
I leave behind the docs, design systems, and automations that let the team keep moving without me in the room. Ownership that doesn't create a bottleneck.

TESTIMONIALS
TESTIMONIALS
"María joined our team 2 years ago to shape ToysReloved's brand design, tone of voice, and UX side by side with me, and quickly became central to how we develop products. She built our 360° brand identity from the ground up and pioneered AI-assisted design and product development on our team – working with tools like Claude, Figma, and our analytical side in ways most designers haven't even started exploring. At the same time, she stays grounded in fundamentals: analyzing data, questioning decisions, and prioritizing what actually moves the business. She combines creativity, curiosity, and commercial thinking in a way that's super beneficial for our organization. Any team would be lucky to have her."
