Freelancer Overview

I am an experienced data annotation and AI training data specialist with a strong background in managing end-to-end localization workflows for AI dubbing projects. My expertise includes refining AI-generated voice models, ensuring emotional accuracy, and performing detailed quality control to meet industry standards. I have worked extensively with automated speech synthesis tools and have a keen eye for maintaining creative integrity while optimizing processes. Additionally, my experience as a database specialist has given me a solid foundation in backend data management, SQL-based analysis, and technical troubleshooting within large-scale, high-stakes environments. My dual academic background in mathematics and cybersecurity, combined with hands-on skills in AI data annotation, equips me to contribute effectively to projects involving natural language processing, speech data, and quality-focused data labeling.

Responsible for producing high-fidelity, verbatim transcripts that capture spoken audio exactly as it sounds, including all filler words, false starts, and repetitions without any grammatical correction or paraphrasing. The role requires acute auditory skills to ensure 100% accuracy, strict adherence to technical tagging for overlapping speech, and the ability to transcribe background speech only when clearly audible. Key performance depends on maintaining linguistic integrity by writing in the speaker's native language and exercising professional judgment to skip or mark files that are unintelligible or in unrecognized languages rather than guessing.
