What I'm looking for

I seek administrative or annotation roles where I can apply public service experience, English fluency, and technical support skills, with opportunities for growth and stable collaboration.

I am an administrative professional and freelancer with a background in municipal public service management and experience as an AI data annotator. I combine administrative support skills with practical IT and technical support experience gained in a law firm.

Alongside administrative roles, I am a professional musician and music teacher, having taught multiple instruments and music theory privately between 2022 and 2024. I also have experience translating and working with English (FISK, Michigan English Test) and maintain fluency in English.

I am currently studying Administration (graduation 2023, Estácio) and seek roles that leverage my administrative, annotation, and multilingual capabilities while allowing continued professional growth in public service or tech-adjacent positions.
