What I'm looking for

I’m looking for work where I can label high-quality datasets, evaluate AI responses for safety and relevance, and maintain top accuracy through rigorous QA, collaborating with teams to refine guidelines and strengthen model reliability.

I’m a detail-oriented Data Annotation Specialist with over 2 years of experience in AI training, data labeling, content moderation, and AI response evaluation. I focus on improving model accuracy and reliability through consistent, high-quality annotation and reinforcement feedback across platforms like LightHouse and Polly.

At LightHouse AI (2023–Present), I annotate and label large datasets to train AI models and conduct AI response evaluations to improve chatbot accuracy. I maintain 98%+ accuracy across tasks and collaborate with teams to refine annotation guidelines, improving model output quality through structured feedback.

Previously at Polly Services (2022–2023), I moderated user-generated content for compliance and evaluated AI-generated responses for safety and relevance. I also transcribed and translated datasets to strengthen training data, contributing to improved system reliability and reduced errors.
