Senior Product Designer
Designing B2B SaaS products from discovery to delivery — working closely with Engineering, Product and Business to turn technical complexity into clear, intuitive experiences.
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.

Testimonials
“Working alongside Sofía was a very positive professional experience. In her classes, she always provides a solid plan of action and is very reliable. She is also thorough in her work without ever losing her warm and friendly demeanor.”
“Working with Sofía makes everything run smoothly. Communication with her is very efficient, and she pays close attention to detail. She’s able to understand complex problems, listen to users, and find ways to meet their needs while maintaining the product’s consistency and brand identity. Plus, she makes day-to-day work more enjoyable and fun. Always on my team!”
“Sofía has many superpowers, but if I had to highlight a few, they would be her ability to work in multidisciplinary teams while taking into account all aspects of the product, her attention to detail, her pragmatism, and her empathy. She does a great job of balancing the more technical aspects with the more human aspects of her work.”
