About

About

I’m Paula Sierra a curious designer with extensive experience in different fields. At my last company, I led UX/UI improvements used by clients like Netflix, Panini, and Meta, leading everything from deep user research to building features, redesigning pages, and presenting interactive prototypes to stakeholders.

Independently I've also crafted designs for startups, restaurant platforms, app interfaces, landing pages, new product features and more. You name it!

I love both sides of design: crafting clean, intuitive interfaces and diving into UX challenges, running A/B tests, and optimising user conversion rates, like solving a puzzle in a design lab.

Challenge me with your project! I'm ready to solve it!

Testimonials

Why Work With Me?
Fast & Affordable!

I love design and some coffee ☕️ - plain and simple. It's what I do best, turning ideas into stunning visuals at lightning speed. Unlike traditional agencies bogged down by meetings and contracts, I cut the fluff and focus on delivering great design.

Here's how it works:

You send your design or sketch idea, share your vision, and maybe include a few examples—that's it. No delays, no bureaucracy—just fast, high-quality work with only the necessary revisions, if needed, to ensure you get exactly what you want.

Great design doesn't have to be complicated or pricey—it just has to work. And that's what I love to do. 🚀

Let's work together!

The first design consultation is free.

Feel free to book a call or email me if you'd like to see my portfolio deck or to discuss a potential project.
