Hi, I'm Karina, UX Design Manager and Product Leader with 10+ years of experience simplifying complex, regulated workflows into intuitive, scalable products, serving users across 70+ country markets in fintech, global payments, and SaaS.
I’ve learned that the fastest way to move products forward isn’t speed. It’s trust.
My work focuses on leading UX strategy and cross-functional teams to turn tangled, compliance-driven workflows into experiences people actually adopt. Trust isn't built through features alone. It's built through care. Care in the small details, care in the language, care in the decisions most users never notice.
Good design doesn’t assume.
It listens first.
Designing across cultures has taught me that what feels intuitive in one context can feel unfamiliar in another. Culture shapes how people interpret risk, language, and flow. The systems we build only work when they respect that.
I stay curious.
Challenges keep me grounded. Currently growing my AI skill set, I’ve earned the Google AI Professional Certificate, and I'm building hands-on experience with Claude. I’m fluent in English and Spanish. I enjoy traveling and learning how other people live and think. Different perspectives open your mind, and that's how ideas come to life. When I’m not working, I’m hiking with my dog Benji or baking, perfecting a recipe on a Sunday.
What it’s like to work with me
