I’m a Detail-oriented Data Associate and Subject Matter Expert with experience at Amazon, where I specialize in quality analysis, computer vision data validation, and performance metrics. I consistently maintain high accuracy standards (above 99.5%) while meeting strict turnaround times.

At Amazon, I led a team of 7–8 members and improved team accuracy performance to 99.6%, reaching a P1 percentile ranking. I monitored daily workflows, optimized operational processes, supported team productivity, and published performance reports (accuracy, takt time, productivity metrics) for stakeholders.

I also worked hands-on as a Machine Learning Data Associate, reviewing and validating computer vision predictions to improve inventory data quality. I identified defects in machine learning predictions, escalated quality issues, and generated leadership-ready accuracy and takt metrics—earning Standing Ovation and White Knights (Legend) recognition, along with a Six Sigma Yellow Belt certification.
