What I'm looking for

I seek roles where I can apply annotation and data expertise to improve AI model quality, work cross-functionally, and drive ethical, impact-focused solutions.

I am an AI enthusiast and data specialist with hands-on experience annotating and evaluating large datasets to improve language model performance and reduce bias.

At Covalen supporting Meta I annotated and labeled datasets, evaluated AI outputs for accuracy and ethical compliance, and collaborated with engineering and research teams to improve model performance.

Previously I worked in global risk operations reviewing legal requests, maintaining confidentiality, and supporting Portuguese–English translation for litigation matters, while contributing to process improvements and quality assurance.

My background also includes customer-facing and operational roles where I developed strong communication, coordination, and data-handling skills, supporting reliable execution in fast-paced environments.
