I design digital products: flows, information architecture and clear interfaces, on scalable design systems. I've applied it in banking, fintech and e-commerce, among others. I start from the problem, not the solution: business context, technical feasibility and user needs. I use AI to speed up the process, audit my designs without bias and reinterpret findings.

A bit of my story

About me

Born in Barranquilla, Colombia, I came to design through my love for illustration. I’ve been a professional graphic designer since 2015, and that visual foundation is still present today in every interface I build.

Since 2018 I’ve been learning about the world of user experience and digital products, and in 2021 I moved into UI design. Since then I’ve worked on design systems, information architecture, complete flows and responsive design proposals, mostly in banking, fintech and e-commerce.

Why work with me?


As Product Designer, I start by understanding the problem before working on the solution. What do I want to solve? Is it worth solving? Who will really use my product? Will the business really benefit from my solution? Designing without a reason is a bad practice: we designers don’t base our work only in designing screens, but on designing solutions bases on the needs and interests of the parties involved.

My goal is that every product I work on balances business, technical feasibility and the user. This starts by understanding the business goals and its model, it’s B2B, B2C, B2B2C, SaaS or something else. Knowing the basics of HTML & CSS helps me design in a realistic way, and I always prioritize solutions that are simple to apply, effective and efficient.

Keeping myself updated with today’s market, AI has become a very useful tool for me: an assistant that helps me speed up repetitive processes, audit my own solutions and ground my ideas.
