What I'm looking for

I seek remote roles supporting AI/ML data pipelines—annotation, transcription, and NLP—within collaborative, quality-focused teams that value accuracy, confidentiality, and professional growth.

I am a tech-savvy data professional with over six years of experience in data annotation, transcription, and AI/ML project support for global remote teams. I combine a strong academic foundation in Linguistics and a Master’s in Data Science with practical expertise labeling text, audio, image, and video datasets to improve model performance and data quality.

I have a proven track record delivering accurate, confidential, and timely datasets for AI applications, including medical transcription and multilingual annotation. I work effectively across international teams, apply rigorous quality checks, and leverage tools like Excel, Python, and R to analyze and visualize data that supports scalable AI solutions.
