What I'm looking for

I'm looking for remote or international data annotation roles where I can apply precise guideline adherence, text labeling, quality review, research, and content categorization to reliable AI training datasets.

At J and F Consultancy, I reviewed, categorized, tagged, and proofread high volumes of written content against detailed brand and editorial guidelines, maintaining consistent quality across remote projects.

I'm certified in Data Labelling & Annotation for AI Development and am building a hands-on annotation portfolio through practical labeling exercises. My background in research, fact-checking, SEO keyword classification, and mentoring junior writers helps me deliver accurate, guideline-driven text and content labeling for AI training data.
