About

Designer, prototyper,
systems thinker.

Hello, I'm Carlos — a Product Designer with 15+ years of experience working on complex, technical problems, finding ways to make them easier to understand and use.

Bio

I've spent 15 years designing for technical products — from digital agencies to startups to large-scale platforms. I started in digital design at Fullsix–Havas, moved into product at Mailjet and Dailymotion, and spent the last six years at Datadog shaping search, security, and observability workflows used by tens of thousands of engineers daily.

I approach design with systems thinking, a comfort with data, and a focus on clarity. I'm drawn to problems where the information is dense, the stakes are high, and the users are experts who need tools that match their speed — not slow them down.

More recently, I've been prototyping with code — building production-grade React prototypes with Claude Code and Cursor instead of static mocks. I believe the best way to validate complex interactions is to use them, not look at them.

I'm curious about how AI can support product design — not just through predictions or personalization, but in helping people reason more effectively in data-heavy contexts. I care about making complex tools feel approachable, and I'm always looking for the next hard problem.
