Info

Driven by curiosity. I believe stories and ideas can change the world, and I bring that belief to life through thoughtful, playful design rooted in research and strategy.

I've been drawing and designing since I was a kid, my mom encouraged my passion by taking me to art classes and other creative activities.

Short reel

At the heart of my work are four design values: usefulness, thoughtfulness, beauty, and craftsmanship. I believe great design solves real needs in meaningful ways—and I’m passionate about shaping experiences that make a measurable, positive difference in people’s lives.

I thrive in collaborative environments where diverse perspectives lead to better outcomes. I move quickly but with care, thinking strategically and executing with attention to detail. Whether zooming out to align with a broader company vision or zooming in on the smallest interface element, I aim to deliver lasting, thoughtful impact.

Design, for me, is about more than solving problems—it's about contributing to something larger.

When I am not designing, probably, I am playing games such as Zelda, Halo, Forza Horizon, Mario and so on or reading The Way of Kings (Cosmere).

Quick bullets:

📖

Reading one book or graphic novel at a time.

🎲

Building forest, roads and cities through amazing board games.

👨🏽‍🌾

I am improving my no-code, business design and management skills… oh, also getting better as farmer.

Experience

I’ve partnered with companies and clients across agency settings and freelance projects, always drawn to teams that value the impact of thoughtful, well-executed design.

I’m César, a Product Designer from Antioquia, Colombia, crafting intuitive interfaces and experiences for teams around the world. With over 10 years of experience, I blend usability, storytelling, and design systems to build user-friendly solutions that drive real impact.

Born and raised in LATAM, I bring a multicultural perspective and a balance of detail and big-picture thinking to every project. I've taught Interface and Experience Design at UAC, and today I’m a Senior Interface Designer helping brands meet their goals through thoughtful, accessible design.

Ten years later, I continue to design with the same devotion and love—to create meaningful impact for people.

My goal is to seamlessly blend aesthetics, functionality, and purpose into unified experiences that tell stories and evoke emotion through powerful visuals and journeys.

Vision

At the heart of every brand or product are people. Understanding their needs, behaviors, and emotions is essential to creating experiences that not only meet expectations—but anticipate them. This human-centered approach builds meaningful connections between users and the brands they interact with.

Design for people. Accessibility and inclusiveness. Stories that move. Design that speaks. Motion that captivates. Images that impact. Unforgettable experiences.

Always beautiful and well made.
