What I'm looking for

I’m looking for fully remote, project-based AI annotation and training work where I can apply strict guideline compliance, fact-checking, and LLM evaluation to improve dataset quality, with clear rubrics, feedback loops, and measurable quality benchmarks.

I’m an AI Data Annotator and AI Trainer with hands-on experience labeling, reviewing, and evaluating diverse datasets—text, conversational data, and structured language content—for generative AI model development. I consistently follow complex annotation guidelines, applying logical reasoning and fact-checking to flag inaccurate, sensitive, ambiguous, or inappropriate material while maintaining zero-error accuracy and meeting project deadlines.

In remote, self-managed roles, I’ve delivered high-volume annotation work using structured written feedback for quality assurance. My experience includes intent classification, sentiment analysis, named entity recognition, and sensitive content flagging, supported by certifications and continuous learning in AI and NLP (IBM SkillsBuild/Cisco Networking Academy, among others), plus a strong focus on guideline compliance and clear clarifying questions to ensure outputs match specifications.
