HELLO!

I DESIGN FOR GROWTH

I design onboarding flows, paywalls, and product experiences that help apps grow.
My focus is in conversion and retention — turning product potential into measurable results.

Design is a strategic tool

Every pixel, word, and motion has a purpose: to guide behavior and create value.

HOW I THINK, DESIGN, AND BUILD

My process is about turning how users and into measurable results.

  • Map behavior to understand why users drop or stay before designing.
  • Design for metrics, with every flow tied to a goal — activation, conversion, or retention.
  • Understand design is a loop and iterate fast.
  • Keep it simple so what matters stands out.

BACKGROUND IN BUSINESS & DATA

Before product design, I worked in business strategy, data, and marketing.

That mix shaped how I think: I don’t separate design from performance.

I build products that look good, feel right, and deliver results.

I think like a strategist, design like a UX/UI, and measure like a marketer.

MY PHILOSOPHY

Design is the bridge between user motivation and business growth.

When it works, you don’t notice it — you just feel it. That’s the kind of design I build: simple, intentional, and built to perform.

I admire her ability to understand what you need, read between the lines and give you more than what you initially ask for. She is an empathetic person capable of putting herself in your shoes, and that, knowing that they care about my project as much as I do, is something you don't usually find.

From day one, Sofia immersed herself in our app, VaultIt, and took the time to understand the emotional core of what we were building. She asked smart questions, challenged assumptions with grace, and brought a product design mindset that went far beyond UI.
