Her early work included voicing the character Pamela Hamster in the series Pecezuelos and Jodie Holmes in the video game Beyond: Two Souls. The COVID-19 pandemic marked a significant shift in her workflow, allowing her to establish a professional recording booth in her home for remote sessions, a change that increased efficiency and became a standard part of her routine.
