Freelancer Overview

I have three years’ experience as a contractor for multiple AI training companies, specializing in high-quality data labeling for LLM and multimodal projects. My work includes Cantonese and Mandarin LLM training (transcription, tokenization checks, and dialect labeling), front-desk reception labeling (intent/slot tagging, call and transcript annotation), challenge prompt write-ups with rubrics to probe model weaknesses, and general data-labeling tasks across text, audio, and image datasets. I’m proficient with tools like Labelbox and Airtable and handle annotation formats (CSV/JSON) with simple Python scripts for validation and preprocessing.
