Designing Better UI/UX Digital Journeys

Here’s a collection of projects where I enhanced the usability, accessibility, and overall flow of digital experiences. Each redesign focuses on creating clearer interfaces, smoother interactions, and more inclusive paths for users—whether on mobile or web.

Hey there!
Diego Sermeño here

Thanks for stopping by!

I’m a multidisciplinary designer from El Salvador, working across UI/UX, marketing design, and motion graphics. I collaborate with teams around the world, bringing a global perspective and a strong commitment to thoughtful, detail-driven design.

I love crafting digital experiences that put people first. From accessible interfaces to engaging social content and motion pieces, I focus on making ideas feel simple, clear, and visually meaningful. I enjoy the entire process—understanding user needs, shaping the flow, refining the visuals, and ensuring everything comes together seamlessly in the final experience.
