Data Annotation Specialist focused on AI response evaluation, screenshot analysis, and high-quality QA.
What I'm looking for
I’m a Data Annotation Specialist who reviews and annotates datasets in line with project guidelines, and I evaluate AI-generated responses for accuracy and relevance. At Sama, I also perform screenshot analysis and UI interpretation tasks, document findings using structured annotation frameworks, and maintain productivity and quality standards while supporting consistent data quality through detailed review and QA Testing adherence.
Previously, as a Content Reviewer at Jumia Kenya, I assessed digital content and product listings for quality and compliance, conducted detailed visual inspections to identify data inconsistencies, and maintained accurate review records and quality metrics. I bring a disciplined, accuracy-driven mindset from my background in information technology and training in Data Annotation & AI Evaluation, with core strengths in quality auditing, strict guideline adherence, analytical assessment, and evidence-based decision making.
