Freelancer Overview

I have extensive experience in AI training data and data labeling through my work as a Medical Product Owner reviewing and validating AI-generated medical content for a health-tech startup. In this role, I evaluated model outputs for clinical accuracy, safety, and alignment with evidence-based guidelines, identifying gaps in reasoning, missing red flags, and potential risks. I also created and refined structured clinical scenarios, workflows, and training examples used to improve model performance, ensuring that outputs were not only correct but also contextually appropriate and safe for use in the real world. What sets me apart is my ability to combine strong clinical reasoning with a structured, detail-oriented approach to data quality, which can be applied to any form of AI training. I am skilled at translating complex medical knowledge into clear, high-quality training data, detecting subtle errors, and improving consistency across outputs. My background in medicine and public health allows me to assess both individual-level clinical decisions and broader ones, making me particularly effective in developing reliable, high-quality AI training data in healthcare contexts. These skills are replicable across other general areas of AI training. My education includes a Master of Public Health from The University of Sheffield and a Doctor of Medicine from Kharkiv National Medical University. Previous AI training focus includes data types such as text and labeling workflows including evaluation and rating.
