Senior UX Designer · Barcelona

I design complex
products for people
who use them every day.

Seven years working in regulated, global B2B SaaS — first at Roche in healthcare diagnostics, then at Clarivate in intellectual property. My work combines user research, product analytics, and close collaboration with engineering and product teams to make things that actually get used.

A bit about how I work

I started in data, as a master data analyst at TD Synnex working in SAP, before moving into UX. That background still shapes how I approach design: I want to understand the numbers, not just the stories people tell in interviews.

At Roche, I worked on diagnostic workflows in a highly regulated environment. That taught me how to design for expert users who don't have time to tolerate bad interfaces. At Clarivate, I've been leading design and research for Derwent Innovation, Clarivate's flagship patent search product.

Outside of day-to-day design work, I've spoken at UX Brighton and UX Nordic, both on the challenge of building trust in AI-powered products, something I think about a lot.

Talking about trust in AI at international conferences

Both talks came from real questions I was wrestling with at work: how do you build a product with AI at its core and still have users trust it enough to actually change their behaviour?

Profile

Senior UX Designer with seven years in regulated, global B2B SaaS, healthcare diagnostics at Roche and intellectual property at Clarivate. I combine user research with product analytics and cross-functional strategy to turn UX into a measurable growth lever. I've designed and tested AI-powered product features at scale, with a hands-on data practice using Pendo and SQL. I'm comfortable owning the full UX cycle: research, experimentation, data-driven iteration, and stakeholder alignment.

Experience
Senior UX Designer Jul 2023 – Present
Clarivate · Barcelona
  • Lead designer and researcher for Derwent Innovation, Clarivate's flagship AI-powered patent search tool for global enterprise customers in IP and life sciences.
  • Owned the full UX lifecycle for AI search capabilities: discovery, feature definition, prototyping, user testing, and post-launch iteration, with direct influence on the product roadmap.
  • Tracked feature adoption, error clicks, rage clicks, and success rates using Pendo; NPS improved following the rollout of a new AI highlighting feature.
  • Initiated a quarterly Feature Health Dashboard with a product analyst, a scoring framework combining adoption rate, usage depth, friction signals, and a composite health score to support data-informed roadmap decisions.
  • Designed and facilitated co-creation workshops with senior stakeholders to align user needs with business goals across multiple product initiatives.
  • Mentored one to two mid-weight UX designers on priorities, critique, and stakeholder collaboration.
  • Led over 30 user research interviews to inform both design decisions and UX hiring.
  • Represented Clarivate as a speaker at UX Brighton 2024 and UX Nordic 2024.
↳ Feature Health Dashboard (FHD) · Self-initiated

I identified a gap in how the department evaluated feature performance and built a process to address it, working with a product analyst to design a repeatable quarterly scoring framework from scratch. It covers feature adoption rate, usage depth, success rate, and friction signals, combined into a composite Feature Health Score. I also designed a 3×3 assessment matrix that categorises features as Core Assets, Growth Opportunities, Critical Quality Issues, or candidates for audit.
