Senior Product Designer
I'm a Senior Product Designer designing complex B2B SaaS products from discovery to delivery. I work closely with Engineering, Product and Business to turn technical complexity into clear, intuitive experiences.
Selected work
Two projects where the most interesting part wasn't the interface. Each one covers the framing, the evidence, the tradeoffs and what I'd do differently.

Resources
The artefacts I actually use, some are for work, others for life.
The spreadsheet I use to track income, fixed costs and monthly spend in one place, with categories and a graph that helps you stay on track and achieve your financial goals
A working document for defining a role end to end — scope, expectations, decision rights and success signals — so the responsibilities of a position are visible before anyone is hired into it.
About
I'm a Senior Product Designer based in Spain, working remotely on complex B2B SaaS products. Most of my work sits in technical domains — water network management, simulation tooling and educational platforms — where understanding the problem is often harder than designing the interface.
I studied Fine Arts before moving into Product Design and I taught drawing and painting for nine years alongside it. That background is essential to how I work: observation first, then structure, then craft.
