Data Analytics Freelancer (Data Labeling/Preparation)
As a Data Analytics Freelancer, I performed extensive data cleaning and pre-processing on diverse datasets to ensure they were ready for analysis and machine learning pipelines. I validated and rectified data inconsistencies, formatted data correctly, and ensured data quality for further modeling. My work included following client instructions on how specific data should be labeled, validated, and annotated to meet strict project requirements. • Utilized Python, R, and Excel for text and numerical data annotation tasks. • Systematically identified and corrected errors and missing values in data. • Followed specific requirements for data integrity and labeling precision. • Communicated data-related findings and ensured deliverables met quality standards.
