About Me
Rafael Castillo | Product Designer & Front-End Developer
I started my creative journey over 8 years ago, diving into the world of motion graphics and visual design. That foundation evolved into a deep passion for building intuitive, high-converting digital experiences — blending creativity with code.
Over the years, I've worked remotely with startups and companies across the U.S., Canada, and London, helping them scale their products with design systems, user-centered thinking, and solid front-end development.
I've led design teams, shaped product strategies, and built tools that not only look great — but perform with purpose. I thrive on metrics, love hitting goals, and bring a collaborative spirit to every project.
If you're looking for someone who blends design vision, technical execution, and strategic thinking — let's talk.
