I am skilled at labeling and classifying complex datasets—ranging from financial transactions and medical communications to blockchain event logs and conversational AI content—using tools like Scale AI, Appen, and Remotasks. My strengths include maintaining high annotation accuracy, upholding guideline consistency, and contributing to rubric development and team calibration. I am comfortable working with structured data in JSON, CSV, and JSONL formats, and I bring strong attention to detail, domain expertise, and a commitment to data quality in every project.
