What I'm looking for

I’m looking for remote-friendly AI/NLP data annotation work where I can follow detailed guidelines, run strong quality checks, and support high-accuracy training data with clear expectations and reliable project direction.

I’m an AI Data Annotation and Data Labelling Specialist focused on language-based tasks and annotation quality for AI systems. I’ve annotated and categorized text, images, audio, and video datasets, supporting AI model training while strictly following project guidelines and quality standards.

I bring exceptional English comprehension and analytical reasoning, strengthened through years of teaching, literacy instruction, and educational assessment. I’m experienced in quality assurance checks, prompt evaluation, and validating data accuracy and consistency, and I work confidently and independently in remote environments with strong time management.
