Freelancer Overview

Within the realm of data labeling and training of artificial intelligence models, my professional journey spans over five years. This duration of work has enabled me to focus primarily on the quality and adherence to guidelines pertaining to training and labeling of medical, text, images, and audio data. My previous designations as a Data Annotation Specialist and AI Training Specialist involved me thoroughly evaluating and correcting the output generated by artificial intelligence models, using complex taxonomy to label the data competently, and offering feedback on correctness and safety. What sets me apart is my hybrid skill set, which includes being a Medical Officer with solid medical background knowledge combined with my experience in AI. As a Medical Officer, I can make an important contribution to medical data annotation work, as my extensive medical knowledge allows me to interpret medical notes, images, test results, and other evidence-based guidelines accurately. I'm highly detail-oriented, proficient in high-volume data annotation, and successful in cross-functional team collaboration. I'm interested in exploring the field of AI, which I'm familiar with.

Multimodal Annotation & Prompt Ranking for AI Training

TolokaVideoEvaluation Rating
Worked with Toloka on large-scale multimodal AI training projects involving text, image, and video annotation, and currently continue to contribute to ongoing tasks. For language model projects, performed prompt ranking and preference labeling, evaluating multiple prompts or AI-generated responses and categorizing the best-performing option based on clarity, relevance, instruction adherence, and guideline compliance. This work directly supports model fine-tuning and reinforcement learning workflows. For computer vision tasks, annotated images and videos by labeling objects, actions, and visual attributes to support object detection, classification, and action recognition models. Ensured high annotation accuracy at both the image and frame level while adhering to detailed task guidelines and quality benchmarks. Maintained consistent performance across high-volume workloads and delivered reliable, high-quality annotations under strict QA standards.
