Freelancer Overview

I have hands-on experience working with structured datasets, where accuracy, consistency, and attention to detail are critical. In my roles in sales and account management, I regularly handled large volumes of customer and transactional data using Excel and CRM systems. I cleaned datasets, standardized entries, and ensured data integrity to support reporting and decision-making. I also built dashboards in Power BI, which required careful validation of data inputs and outputs. I have developed strong pattern recognition and quality control skills through data analysis tasks. I worked with sales and operational data to identify trends, flag anomalies, and maintain high data accuracy standards. I am comfortable following strict guidelines, meeting deadlines, and maintaining consistency across repetitive tasks. My experience with Excel, SQL, and data visualization tools gives me a solid foundation to contribute effectively to data labeling and AI training workflows.
