As an independent contractor, I have specialized in search and ad evaluation, image labeling, and data quality assurance, consistently delivering high-quality outcomes.
Currently, I work as an AI Trainer at Outlier.Ai, where I evaluate AI-generated responses to enhance model performance. My role involves designing prompts that align with project requirements, ensuring clarity and factual accuracy. Additionally, I have experience as an Ads Quality Rater at Welocalize and as an Independent Contractor with Appen, where I have honed my skills in assessing search engine relevance and optimizing ad placements. I am enthusiastic about leveraging my expertise in data analytics and AI to drive innovation in clinical annotation and labeling projects.
