Freelancer Overview

Experienced in RLHF and SFT projects, I can grasp client intent and demands from complex documentation. My expertise in Political Science provides me necessary exposure and context to work in projects within sensitive categories. I have experience working with various data annotation architectures across multiple platforms, and can adapt to new environments readily. I have obtained strong writing and research skills from my education in the humanities domain. I have worked as a senior reviewer in multiple projects, which attests to my attention to project requirements. I have learnt to write concise and clear feedback when reviewing work.
