Freelancer Overview

I am a detail-oriented data professional with hands-on experience in AI data training, data labeling, and quality assurance for AI models. My work as an AI Data Trainer for Invisible Technologies and Outlier involved evaluating, rating, and validating AI-generated outputs, providing structured feedback, and ensuring data accuracy and consistency according to project guidelines. I am skilled in data cleaning, formatting, and validation using tools like Excel, Google Sheets, and SQL, and have a strong foundation in data science and analytics. My background includes managing digital records, documenting results for internal quality tracking, and collaborating with teams to maintain high data standards. I am adaptable, reliable, and passionate about supporting AI development through meticulous data annotation and validation.

I worked on multiple projects under Outlier.ai. There was always short course material provided on what will be required on the project, the pay rate and expected task duration. The material would also include knowledge test or quizzes, that would ensure experts understood the project requirements.
