Freelancer Overview

I am a Chemistry with Medicinal Chemistry graduate with hands-on experience in pharmaceutical research, laboratory data analysis, and advanced analytical techniques. My recent roles have focused on AI training data, including evaluating and refining outputs for large language models (LLMs) across STEM, video, image, and language domains. I have led teams in annotating and validating chemical equations, mechanisms, and computational results, ensuring scientific accuracy and adherence to industry standards. My background includes developing and quality-assuring complex, real-world chemistry questions for AI models, as well as collaborating with interdisciplinary teams to improve generative AI performance. I am skilled in data analysis tools such as Excel and MATLAB, and have a strong foundation in computational chemistry, making me highly adaptable to diverse data labeling and annotation tasks in both scientific and technical domains.

Project Anton

MercorImagePrompt Response Writing SFT

This project analysing a prompt in English and another language (expert's second language) alongside a picture, a model response and rubrics. Our job was to correct any inconsistencies, ensuring there were minor or major errors found in any of the pieces of text. For example, one way we would do this is by making sure that the rubrics were exhaustive while completely atomic.
