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
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.

03
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
"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."
