EXPERIENCE
Helping global teams improve Spanish language quality and evaluate multilingual AI for Mexican and US Spanish audiences.
I have worked at the intersection of language and technology since 2004. My experience spans e-commerce, retail, software, apps, and digital communications, where I help teams create accurate, culturally relevant Spanish content and evaluate the language technologies behind it. My principal areas of specialization are Mexican Spanish (es-MX) and US Spanish (es-US). Although these audiences share a language, they do not necessarily share the same terminology, cultural references, expectations, or communication patterns. Effective localization treats each one on its own terms.
Areas of expertise
Localization strategy and leadership
I connect linguistic requirements with product priorities and business goals. My experience includes leading teams of up to 12 linguists, defining workflows, guiding language decisions, coordinating resources, and establishing quality standards for complex, high-volume programs.
Multilingual AI evaluation
I evaluate AI-generated and machine-translated content for meaning preservation, terminology, fluency, cultural suitability, and fitness for purpose. I also help define evaluation criteria, identify recurring failure patterns, and turn linguistic findings into practical improvements.
Language technology and cross-lingual search
I apply linguistic expertise to NLP evaluation, query adaptation, and multilingual search relevance. This work helps preserve user intent, account for language variation, and protect names, brands, product terms, and other essential entities as information moves between languages and locales.
Internationalization and product localization
I help teams identify language and locale requirements early in the product lifecycle. My experience includes software interfaces, dynamic product catalogs, and localized digital content, where linguistic decisions directly affect clarity, findability, and consistency.
From linguistic findings to better decisions
My approach is collaborative and evidence-based. I translate linguistic findings into clear recommendations for the people building, managing, and evaluating multilingual products.
Rather than treating individual errors in isolation, I look for patterns that can improve guidelines, workflows, evaluation methods, and product decisions. My goal is to help multilingual products feel clear, relevant, and trustworthy to the people who use them.

ABOUT ME
I've always been curious about people, places, and the different ways we each try to make sense of the world around us. I grew up in a big, fairly chaotic family with three sisters and five brothers, and from an early age I learned how much you can discover by listening closely, paying attention, and staying open to perspectives different from your own.
That curiosity never really went away. I love reading, especially fiction, and I have a particular weakness for trivia, obscure facts, and those seemingly useless bits of information that somehow only make me want to know more. I enjoy following an idea simply because it interests me, even when it sends me down an unexpected rabbit hole into history, science, language, technology, or some conspiracy theory I never meant to investigate in the first place.
I recently studied Cinematic Arts, although I’ve loved movies for as long as I can remember. I’m especially fascinated by the way film can capture an era, a culture, or a particular way of seeing the world. Books, movies, and politics have each, in their own way, given me a window into realities beyond my own.
I divide my time between Mexico and the United States, and I value the perspective that comes from moving between places, cultures, and different ways of understanding life. Travel, the life sciences, geopolitics, technology, coffee, a good book, and the small rituals of everyday life are all part of what keeps my curiosity alive.
More than anything, I’m someone who likes to keep learning, asking questions, and finding connections between things that, at first glance, may not seem connected at all.
