Freelancer Overview

After completing a Bachelor of Science in Psychology at the University of Manitoba, I transitioned into AI training and data annotation, where I have been working steadily since April 2024 across a wide range of projects and engagements. My work spans Reinforcement Learning from Human Feedback (RLHF) and Supervised Fine-Tuning (SFT) for Large Language Models, as well as multimodal annotation across text, image, audio, and video modalities. I have contributed to preference ranking workflows, prompt engineering, response evaluation, text-to-speech model assessment, and quality control — consistently maintaining high accuracy and throughput across large-scale annotation pipelines. What sets me apart is a combination of academic training and practical versatility. My background in psychological research gave me a strong foundation in systematic evaluation, data analysis, and structured judgment — skills that translate directly into producing reliable, consistent annotation at scale. I have worked across numerous simultaneous engagements, adapting quickly to varied annotation schemas, guidelines, and task types while operating under strict NDA confidentiality. I also bring quality assurance experience, having reviewed and provided feedback on other annotators' work to maintain data integrity across teams.
