What I'm looking for

I seek remote, project-based roles in AI data annotation, search evaluation, or social media moderation where I can apply rigorous QA, follow detailed guidelines, and improve model training data.

I am a computer scientist with hands-on experience in AI data annotation, search evaluation, and social media fact-checking. I excel at following complex rating guidelines, identifying biases and inconsistencies, and producing high-quality labeled datasets to improve AI performance.

I have worked remotely on search engine evaluation and social media moderation projects, and I bring strong pattern-recognition, time-management, and independent-project skills. I am multilingual and certified in AWS Cloud Practitioner and ISC2 cybersecurity, and I consistently focus on accuracy and scalable processes.
