My 18 years of experience working with renowned organizations as an in-house translator, as well as a freelancer, allow me to have a vast background in my main languages. I specialize in these services:

Localization: beyond translating content, I translate and adapt experiences for the Mexican market and high-end product and service consumers. I understand the cultural nuances, linguistic subtleties, and local preferences that ensure authentic and impactful communication.

Linguistic Validation (LV): as a Linguistic Validation Consultant (LVC), I assist researchers and Contract Research Organizations (CRO) in validating their Clinical Outcome Assessment (COA) instruments; from translatability to harmonization in Spanish for Mexico (es-MX), and the United States (es-US).

Computational Linguistics: I use technology and Machine Learning (ML) to optimize translation workflows, enhance accuracy, and improve efficiency. I stay at the forefront of innovative tools and methodologies to deliver consistently high human-produced quality results.

Subject Matters: extensive experience in technology, software, marketing, law, medicine, life sciences, and Machine Learning Large Language Models (LLMs). I handle complex projects with confidence and deliver translations and revisions that are accurate and culturally sensitive.

With my Client-focused Approach, I focus on exceeding my client's expectations by delivering reliable, high-quality human translations that seamlessly integrate into their market strategies.

I practice open communication and understanding throughout the entire project lifecycle. Feel free to share your project needs, and let’s talk about how I can assist.

Linguistic Validation



I spend my time between the picturesque neighborhood of Coyoacán, in Mexico City, and my hometown Ciudad Obregón, in the State of Sonora, Northern Mexico. As a dedicated full-time freelancer, I work from my cozy home office. My passions span languages, traveling, life sciences, research, and geopolitics. Growing up in Sonora, I shared a bustling yet loving household with three sisters and five brothers! My upbringing in a large, lively family instilled in me the importance of clear communication and cultural understanding.
