Freelancer Overview

I have hands-on experience in media transcription and subtitling, where I transcribed and time-coded audio content to create accurate, publication-ready subtitles. My work required a high level of linguistic precision, attention to detail, and consistency in tone and formatting skills that are directly applicable to data labeling and annotation for AI training data, especially in natural language processing and computer vision projects. I am adept at managing and editing content for diverse platforms, collaborating with teams to ensure quality and alignment with project goals. My background in content creation, branding, and social media management has strengthened my ability to handle large volumes of data, maintain accuracy, and meet tight deadlines, making me well-suited for roles in data annotation and AI training data preparation.
