Freelancer Overview

I bring over 15 years of experience in audio postproduction, sound design, and voice editing, which has equipped me with a highly trained ear, attention to detail, and a deep understanding of nuance—skills that translate naturally into high-quality data labeling and AI training work. My background in working with complex sound environments and scripted content has refined my ability to recognize patterns, inconsistencies, and context with precision. I’ve contributed to award-winning audiovisual projects and worked across diverse formats, from documentaries to podcasts and animation, always maintaining a high standard of accuracy and consistency. I’m reliable, focused, and comfortable working independently to meet tight deadlines—ready to support AI systems with clean, consistent, and meaningful data.
