What I'm looking for

I seek roles leveraging multilingual communication, AI training, and program coordination in multicultural teams, with opportunities for impact and professional growth.

I am a multilingual international studies professional with experience in AI training, interpretation, program coordination, and international development. I combine academic research on global issues with practical fieldwork and client-facing roles across Japan, Mozambique, and Portugal.

As a freelance AI trainer and language specialist, I create and optimize Japanese prompts, annotate model outputs, and verify facts to improve model performance while collaborating with cross-functional, distributed teams. My background includes consecutive interpretation for large-scale projects, translation of technical documents, and organizing programs and training for diverse stakeholders.

I have led community and development activities, managed logistics for international conferences, and supported sales and client relations in commercial roles. I bring strong cross-cultural communication, project coordination, and research skills, and I am motivated to apply these strengths in roles that value multilingual expertise and evidence-based program delivery.
