Outcome-based engagements—research, experiments, and delivery support. Based in Madrid, working worldwide.
Senior UX Product Designer ・ MBA ・ 10+ years
I help founders and product leaders make better product decisions under constraints—so teams ship coherently and can measure what changed.
I work end-to-end across B2C growth and B2B SaaS, including operations-heavy platforms and public-sector constraints—Privacy, Secure & Accessible by Design.
Every engagement follows the same loop: evidence → trade-offs → prototype → ship with instrumentation → iterate.
A focused engagement with a defined output: a clarity sprint, an audit, or an experiment framework. Best when you need a clear answer fast.
End-to-end design and delivery support for a defined scope: a new feature, a redesign, or a v1 launch. Includes research, prototyping, specs, and iteration after release.
Lightweight, ongoing support: design reviews, decision check-ins, and strategic input on a regular cadence. Best for teams with internal design capacity.
I work directly with engineers—reviewing PRs, pairing on edge cases, and writing specs they can build from. Design is only useful if it ships, so I stay close to implementation.
Yes, when it accelerates learning. I build working prototypes, front-end components, and CLI tools to validate flows before committing engineering time. I also contribute to design system code.
I work under NDA regularly. Case studies on this site are published with explicit client permission; confidential work is described without naming the client.
Depends on the engagement: activation, conversion, retention, task completion time, error rates, escalation frequency, time-to-first-success (for developer tools). I define the metric at the start and instrument it before release.
Madrid, Spain. I work remotely with teams across Europe, and I'm available for on-site workshops when needed.
Describe your constraints and the decision you need to make. I'll tell you if I can help.
