Emotion Recognition

Freelancer Overview

I am an experienced data annotation and AI training specialist with a strong background in multilingual data labeling, quality assurance, and localization.

I have collaborated with engineers and cross-functional teams to refine annotation workflows using proprietary labeling tools and have consistently delivered high-quality datasets through rigorous QA processes. My expertise includes resolving linguistic ambiguities, reviewing AI-generated translations for tone and intent, and supporting the development of multilingual evaluation benchmarks for NLP and localization projects. I am passionate about ensuring that AI systems understand and respect linguistic and cultural nuances.
