Freelancer Overview

Most of my experience is in audio labeling for AI training, especially conversational voice data where an AI and a person are talking. I usually work at a very detailed level, marking and labeling speech segments with precise timestamps, often down to milliseconds. The work needs patience and accuracy, and I’m comfortable spending long hours making sure everything lines up correctly with the guidelines. I’ve also done image evaluation and text quality checks, mainly reviewing things like capitalization, formatting, and basic consistency. I’ve worked on platforms like iMerit, Data Annotation Tech, and Labelbox, so I’m used to structured tasks, clear instructions, and quality feedback. I take the work seriously and try to deliver clean, reliable annotations rather than rushing through tasks.

Receipt and Document Evaluation for AI Training

Data Annotation TechImageClassification

I worked on a document evaluation project focused on training AI models to correctly identify valid receipts. My role involved reviewing receipt images and classifying whether an image was a receipt or not, as well as checking for duplicate submissions. The work required careful visual inspection, attention to detail, and strict adherence to task guidelines to avoid incorrect classifications. Quality checks and consistency were important throughout the task.
