What I'm looking for

I am seeking annotation roles where I can apply meticulous labeling skills, work with multimodal datasets, collaborate with teams, and contribute to reliable ML data while growing in data quality responsibilities.

I am a detail-oriented Data Annotation Specialist with hands-on experience labeling and organizing datasets to support machine learning and AI model development.

I have worked across image, text, audio and multimodal projects, using tools such as Single Review Tool, Multimago Tool, and Matrix Tool to ensure consistent, high-quality annotations.

As a freelancer I completed projects including misinformation rating (Uolo V2), audio reference-matching (Project Coffee), image reference-matching, and video reference-matching, demonstrating strong attention to detail and ability to meet tight deadlines.

I collaborate well with teams, prioritize data compliance and accuracy, and apply annotation guidelines consistently to help improve model performance and data reliability.
