Freelancer Overview

I am an experienced data annotator and data analyst with a strong background in labeling and validating large datasets across text, image, audio, and video domains for machine learning and AI model development. My work has focused on ensuring high data quality and consistency, collaborating closely with data scientists and engineers to deliver robust training data for projects in computer vision and NLP. I am skilled in Python (Pandas, Scikit-learn, TensorFlow), SQL, Excel, and Tableau, and have a proven track record of identifying patterns to enhance model accuracy and supporting data-driven decision-making. My experience includes implementing quality checks, developing machine learning models, and guiding junior team members to maintain best practices in data annotation and analysis.
