UX/UI Designer with a Senior level in UI, a solid UX foundation, and a product mindset — from discovery to delivery. I design clear interfaces and scalable systems for banking and fintech products.

Before designing, I work the problem first: KPIs, business context, and technical feasibility. I collaborate with product and engineering teams in Agile/Scrum, with the technical judgment (HTML/CSS) to propose buildable solutions, and I use AI intentionally — including prompt engineering — to research, make better decisions, and move faster.

My work

Featured projects

A selection of projects where I applied UX and interface design — research, flows, systems, and product decisions — to digital products in banking, fintech, and e-commerce, caring for experience, usability, and system consistency.

A bit of my story

About me

I was born in Barranquilla, Colombia, and came to design through illustration. I've been a professional graphic designer since 2015, and that visual foundation is still present in every interface I build.

In 2021 I moved into UI design and established myself at a Senior level in UI, bringing UX work into the entire process — research, information architecture, flows, and usability testing — until I became comfortable working as a UX/UI Designer, with a product perspective that goes beyond the screen.

From Pragma, I've worked for clients such as Bancolombia, Banco Itaú, Redeban, and Grupo Mutual — most in banking and fintech — contributing to their digital products and design systems. Along the way I've practiced the different phases of the product process — discovery, design, and delivery — in real scenarios, learning that impact happens when business, user, and technical feasibility are balanced.

Why work with me?


As a UX/UI Designer with a Senior level in UI and a product mindset, I turn complex problems into clear, functional, user-centered interfaces. I start with the problem — KPIs, the current state of the product, its relevance to business and users, and technical or budget constraints — before proposing solutions.

I design iteratively: from sketches and wireframes at medium to high fidelity, validating with research and usability testing, and involving the development team from the start to avoid technical surprises. I close with a clean, documented handoff — components with tokens and variables, and clear interactive prototypes.

I've worked across B2B, B2C, and B2B2C contexts, leaning on Design Systems, technical judgment (HTML/CSS), and AI tools — with prompt engineering — to create faster, higher-impact solutions. I adapt easily to teams or work independently, bringing judgment and results from day one.
