What I'm looking for

I'm seeking remote AI training, customer support, data entry, or virtual assistant roles where I can contribute immediately and exceed performance targets.

At Scale AI, I train and evaluate large language models by labeling more than 2,500 data points daily with 99.2% accuracy. My work includes sentiment analysis, entity recognition, and prompt response scoring, which reduced error rates by 35%.

At Crowdgen, I supported 80–100 customers daily through phone, chat, and email, achieving a 97% customer satisfaction score. I also resolved technical and billing issues and upsold retention packages that generated $18,000 in additional monthly revenue.

As a Data Entry & Processing Specialist with Amazon Mechanical Turk / CrowdGen (Formerly Appen), I entered and verified more than 1,200 records per shift and completed transcription and categorization projects. I also identified and corrected data discrepancies that saved clients an estimated 120 hours of rework.

In my freelance and Boldly Virtual Assistants work, I supported three executives by managing calendars, travel, and more than 150 weekly emails. I also maintained client databases and created presentations and graphics in Canva.
