Hi, I’m Ruben Cespedes—Principal Product Designer at Dell Technologies, Adobe Partner, and mentor to over 215k+ designers around the world.

With 20+ years of experience in UX design, product design, and visual design, I help turn complex ideas into intuitive, human-centered digital products. My work focuses on Figma workflows, accessibility, design systems, and building UI that’s both beautiful and functional.

I’m also the author of two books:
• Conquering UI Design – a practical guide to UI principles, structure, and visual clarity

• The Self-Made Portfolio – released in early 2025 to help new designers overcome the overwhelm of building their first portfolio. It’s packed with real examples, templates, and honest advice based on what hiring managers actually look for.

On Skillshare, I teach hands-on, beginner-friendly classes that cover everything from UI color theory to portfolio feedback. My goal is to help you grow with practical lessons, not fluff—so you can design with confidence and clarity.

Let’s simplify design, one skill at a time.
