Hey—I’m Ricardo. I’m a Senior Web & Product Designer who builds clean, accessible, dev-ready interfaces for data-dense products and websites. I work end-to-end: design systems, IA, wireframing, prototyping, accessibility, and production HTML/CSS for reliable handoffs (Zeplin). I’m not a developer—I work closely with developers to ensure that high-quality products are released efficiently. I care about results and craft. **Highlights:** * At Check ’n Go I improved homepage load time by 84%, reduced page weight 42%, and dropped HTTP requests 89%. * At LexisNexis I shipped 2 global redesigns and 30+ localized sites. * I’ve also mentored 150+ designers with consistent 5★ reviews. Accessibility is a big deal to me. I built [Color-Ramp.com](http://color-ramp.com/) to solve a real gap: creating OKLCH/HSL color ramps that guarantee WCAG 2.1 AA/AAA in both light and dark UIs. I also co-created [AspireMap.ai](http://aspiremap.ai/), a B2C platform that helps students and career-changers find career paths aligned with their values, personality, aptitudes, and skills.

_Better to learn something is to start explaining things._ I started with answering questions on Stackoverflow some time ago, all my answers lead to communication with topic's starter and end up with posting a working code example. I want to help, because I learn something new, because today is hard to find people out there at some meet-ups and find out what interesting projects they are working on.
