I do my best work on problems I believe in.I’m looking for the next one.

I’m a Principal Product Designer who spent almost a decade at TripIt — on purpose. I care deeply about the work, I move fast, and I’m told I can look intimidating until I start talking. My friends say it’s because I’m always thinking.
For what it’s worth, I’m also very small.


Kind words from awesome people.

After working with Kat for nearly 10 years, I would recommend her without hesitation to any team looking for an exceptional product designer. She has terrific instincts, deep expertise across web, mobile, and design systems, and a rare ability to collaborate effortlessly with designers, product managers, and engineers alike— always keeping the user at the center and asking the insightful questions that make every project stronger. She's also a wonderful mentor to other designers, generous with her knowledge and committed to helping the people around her grow. Kat consistently raises the bar for those around her and brings the full package: craft excellence, creative product thinking, and generous, trusted partnership.

Kat, I know this year has had its struggles and challenges, but I really value how you've been such a pillar for the team through it all. I always know I can rely on you to keep things moving forward smoothly, even when things are uncertain, and you consistently bring great design thinking and high-quality work to the table. Of course, I also deeply appreciate your strong collaboration with product and engineering partners—you build trust, communicate clearly, and help bridge gaps that make projects run more smoothly and generally just make things easier for everyone! You've been leading the way for TripIt design in a meaningful way, setting a strong example with your reliability and expertise.

Kat, when we became part of the same team, I told you I respected your work and was looking forward to partnering with you. You lived up to every bit of what I was hoping for in a partnership. I really admired how well you communicate, how thoughtful your designs were, how much you listened and included different perspectives, and how well you navigated strong opinions. We had so many plans for the future and we were just about to hit our stride. I wish you all the best in your career and will keep in touch. We are TripIt family.

Kat consistently manages everyone's valuable time in UX Design Review meetings by keeping the focus on critical discussions and decision points, documenting questions and actions in Figma to ensure all questions and feedback are tracked and addressed, and by steering conversations away from side topics and towards generating consensus on the designs needing review. She also continues to put the user front and center in evaluating the effectiveness of design decisions while taking the time to understand and accommodate technical limitations of each platform.

Hi Kat, I just wanted to say thank you for these amazing years of work we had together. My sister is also a designer so I learned a lot about it from her, specially how much to appreciate the design area, but she has just recently migrated to the UX area. You were always the example of a great UX designer that I shared with her. It was one of the favorite parts of my work to participate in design and product meetings, hearing you explain why something should be one way or another, sharing examples and research, I've learned so much from you. Thank you for everything! TripIt will not be the same anymore.

If something was missing, if a case study lacked context, or if you just want to debate the merits of Baldur’s Gate 3 mechanics, I want to hear about it.
