About
A little more context
I’m Carlos, a New York-based frontend engineer working between design and engineering. I specialize in translating product design into polished, accessible interfaces that hold up in production.
Over the past several years, I’ve worked across cybersecurity, health tech, education, developer tools, and consumer product experiences, building interfaces that balance usability, craft, and engineering quality.
Outside of product work, I’m drawn to creative projects, visual experiments, travel, music, and documenting the small details that shape taste and perspective.
