What I'm looking for

I’m looking for roles where I can produce accurate, well-formatted transcripts and reliable labeled data, support AI/ML training with strong quality assurance, meet deadlines on large datasets, and collaborate with international teams.

I’m a detail-oriented Data Annotator, Transcriber, and Transcriptionist with over 9 years of experience working on online AI platforms. I annotate and label text, image, audio, and video data for AI and machine learning projects, and I transcribe audio recordings with high accuracy and proper formatting.

I’m especially strong in quality control—I review and correct transcription output to ensure quality standards, and I perform data review, quality assurance, and AI training data preparation. I also manage multiple assignments while meeting strict deadlines, maintain confidentiality with sensitive information, and collaborate remotely with international teams and project managers.
