Freelancer Overview

I have hands on experience in AI training and data labeling, specifically with audio-based RLHF projects. Over the past few days, I have completed 200+ audio annotations, focusing on transcription, response evaluation, and quality control to help improve AI models. I am a fast learner with strong attention to detail and a good acceptance rate. I quickly moved from Base to Bronze tier, and I am now working toward Silver and Gold tiers. My background in game development also helps me approach tasks with problem-solving and consistency, ensuring high-quality labeled data for AI training.
