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 me by taking me to art classes and other creative activities.

Short reel

Short reel

Four things guide my work: usefulness, thoughtfulness, beauty, and craftsmanship. I want what I design to address real needs and make a measurable difference in people’s lives.


I enjoy working with people who bring different perspectives to the table. I move quickly and carefully, thinking about the broader company vision as well as the smallest interface details. I want the work to have a lasting impact.


For me, design is also a way to contribute 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.

Layers

I’m César, a Product Designer from Antioquia, Colombia. For over 10 years, I’ve worked with teams around the world to create intuitive interfaces and experiences, bringing together usability, storytelling, and design systems to make a real impact.


I was born and raised in LATAM. I bring that perspective to my work, paying attention to both the details and the bigger picture. I’ve taught Interface and Experience Design at UAC. Today, I’m a Senior Interface Designer helping brands reach their goals through thoughtful, accessible design.

Ten years later, I still love designing and care about making a meaningful difference for people.

I want to bring aesthetics, function, and purpose together in experiences that tell stories and evoke emotion through visuals and journeys.

Vision

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.
