About

I am a professional AI Trainer and Data Annotator with around 3 years of experience in processing, labeling, and validating high-quality datasets for AI development. Holding a Bachelor’s degree in Anthropology, I bring a unique perspective to the tech industry—deeply understanding cultural nuances, human behavior, and social contexts, which are essential for training unbiased and human-centric AI models.

My technical expertise is backed by certifications in Artificial Intelligence Fundamentals and Data Analytics Fundamentals, alongside a specialized Linguistic AI Certification Training from RWS. This powerful blend of skills enables me to perform high-precision data annotation, analyze complex linguistic data, and optimize Large Language Models (LLMs). I am dedicated to bridging the gap between human culture and technology by delivering accurate, ethical, and context-aware training data.
