Freelancer Overview

I have hands-on experience in data labeling and AI training across text, audio, image, and map-based projects. Through my work with DataForce and OneForma, I’ve contributed to large-scale NLP, speech recognition, and geospatial annotation tasks—ensuring linguistic, contextual, and cultural accuracy in multilingual datasets. My work has supported the development of more precise and inclusive AI systems. What sets me apart is my blend of linguistic expertise and analytical discipline. With a background in Applied Linguistics and Data Communication, I bring structure, consistency, and attention to detail to every project. I’m skilled in annotation tools, data validation, and quality assurance, and I thrive in remote, cross-functional environments focused on improving AI model performance.
