What I'm looking for

I’m looking for a role where I can apply my guideline-based quality assurance and fact-checking skills to improve data accuracy, train better ML outcomes, and work with a team that values clarity, compliance, and continuous process improvement.

I’m a quality-driven, detail-oriented professional with extensive experience across human resources and data annotation. I enhance data accuracy, consistency, and compliance with standards by evaluating responses for accuracy, relevance, and consistency with provided guidelines, and by conducting detailed fact-checking of claims using credible sources.

In my LLM and ML data annotation work, I review annotated content for clarity and coherence, compile evidence and sources to validate or reject claims, and collaborate with cross-functional teams to improve annotation processes. I also bring a strong operational discipline from HR—developing recruitment strategies, managing onboarding, handling disciplinary issues, and supporting retention—while maintaining a balance between speed and precision and adapting quickly to new annotation tools and platforms.
