Freelancer Overview

I am a detail-oriented linguistics and AI enthusiast with hands-on experience in language data annotation, transcription, and supporting natural language processing projects. My background includes working with multilingual datasets, labeling data for AI model training, and conducting linguistic analysis at both the phonetic and syntactic levels. I am skilled in using Python (with basic knowledge of NLTK and spaCy) for data processing, and I have contributed to improving dataset accuracy and consistency through collaborative teamwork. My academic foundation in linguistics and computational linguistics, combined with certifications in AI and NLP tools, enables me to deliver high-quality annotated data and insightful research for language technology projects.
