Let’s build something people trust
Hi, I’m Karina Guzman, a UX Design Manager in fintech and global payments. I turn complex, regulated money flows into products that help people send money home across 70+ markets.
uLink SuperApp
Rebuilt a cross-border money transfer app into one place to send money, pay bills and manage a wallet. Fewer steps, fewer errors, more repeat senders.
UniTeller Digital Link
A white-label platform that lets banks and partners launch their own branded remittance app, from onboarding to first transfer.
Oh My Card!
Launched a new gift card app for customers in Guatemala after an acquisition, from concept to a full mobile experience.
UniTeller Website
Turned a legacy fintech site into a clear showcase for our solutions, built to support sales and new partnerships.

What it’s like to work with me
I have been working closely with Karina for the past 4 years at UniTeller. Karina has demonstrated initiative in making value-orientated designs, having passion for her field of work, and making good use of her creativity. Her proposals go beyond expectations. She is a highly qualified professional who enjoys her work and creates value for the company.

I have worked with Karina for two years at UniTeller. She is knowledgeable, driven, and enthusiastic UI/UX Designer. In the years I have worked with her I’ve seen her take on many projects and succeed. Aside from being a pleasure to work with she’s been a great friend! I 100% recommend Karina!
Candy A. - Monetization & Strategy, Advertising Operations at TikTok
Karina is one of the best UI/UX designers I know, efficient and very methodical when it comes to working, always up-to-date and finding the best solution. She is a very connected with her environment and her colleagues, she likes to travel and venture into the unknown, which makes her much more creative and she solves problems in different ways, giving incredible results.
Jeisel H. - Branding Designer and Yoga Instructor
Karina is a great UX designer and professional. She has a great ability to apply her experience to make thoughtful decisions and solve complex problems effectively. In addition to her strong knowledge, her sense of responsibility ensures that projects move forward smoothly. While her creativity, adaptability, and leadership contribute greatly to creating a positive and collaborative work environment.

More than the resume…
Behind every compliance rule is a person just trying to get something done.
I’m usually the one in the room asking why a step exists and who it’s really for. I like taking messy requirements and turning them into something a team can build and a customer can finish without help, and I still love doing the design work myself. Lately I’m growing my AI skills: I earned the Google AI Professional Certificate, and build hands-on with Claude.
I stay curious.
Challenges keep me grounded. I studied design in Mexico and Spain, and later moved to Texas to earn my master’s in Information Technology. 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.

Complex systems don’t scare me.
What interests me is the human behavior inside them.
