KenyaWhat I'm looking for
I’m a detail-oriented Evaluation & Annotation Analyst with 10+ years of experience assessing quality, accuracy, and reasoning across AI-generated outputs and annotated datasets. I specialize in side-by-side (SxS) evaluations, rubric-based scoring, fact-checking, and producing clear, evidence-backed justifications that teams can trust.
I’ve built and delivered audit-style review workflows and annotation QA pipelines using structured guidelines and quality standards—often combining browser-based evaluation tools with lightweight command-line approaches. From 2022–present, I’ve done multi-domain transcript QA and AI post-editing, maintaining 99%+ accuracy while staying compliant with HIPAA and GDPR; I’ve also delivered 10,000+ hours of transcription work with 100% client retention.
