Freelancer Overview

My AI training skills cover a wide range of areas, including RLHF, evaluation and rating of two-model responses, audio recording, annotation, transcription, and SFT. My strongest skills are in Evaluation and RLHF. I specialize in designing effective prompt engineering and creating rubrics that optimize model learning.

I review pre-written prompts along with two corresponding responses, evaluate each response, provide feedback that reflects human reasoning, and determine which one is superior.

I recorded short audio clips of about 20 seconds according to assigned categories, transcribed the recordings, classified them based on their purpose (such as whether they were knowledge-seeking or casual conversation), and evaluated their noise levels.
