What I'm looking for

I seek a role that allows me to leverage my linguistic expertise in AI, fostering growth and innovation in language models.

I am a linguist with a Master’s in Linguistics from Universidade Estadual Paulista (UNESP) and a Bachelor’s in Portuguese Language & Literature from Universidade Federal de São Carlos (UFSCar). My academic journey has equipped me with a deep understanding of phonetics, syntax, semantics, and sociolinguistics, which I apply in my professional endeavors.

Currently, I work as a Freelance Linguistic Evaluator and Prompt Tester, where I evaluate AI-generated responses in Portuguese, ensuring grammaticality and cultural accuracy. My experience as a Portuguese Instructor has allowed me to design effective learning materials and teach advanced grammar to international professionals. I am passionate about contributing to the evolution of AI language models through expert linguistic insights and rigorous prompt testing.
