Freelancer Overview

I am an experienced AI and LLM specialist with a strong background in data labeling, annotation, and model evaluation across text, image, video, and audio formats. My hands-on work spans leading platforms such as Mindrift, UHRS, Oneforma, Appen, and TestIO, where I have contributed to prompt engineering, search relevance optimization, and large language model (LLM) behavior refinement. I am skilled in Chain of Thought (CoT) reasoning, multilingual data annotation, and quality assurance, ensuring data accuracy and model alignment for diverse AI projects. My expertise covers the use of advanced annotation tools like Labelbox, CVAT, and Supervisely, as well as QA and bug tracking systems such as Jira and TestRail. I am fluent in English, Yoruba, and Nigerian Pidgin, which allows me to work on multilingual data projects, and I am committed to delivering high-quality, reliable training data for machine learning and AI development.

Senior AI Tutor & Expert Annotator

MindriftTextRLHFFine Tuning

As a Senior AI Tutor & Expert Annotator at Mindrift (Toloka AI), I conducted Chain of Thought (CoT) evaluations for logical consistency and factuality in reasoning tasks. I annotated and evaluated text, image, and video data to enforce safety and alignment, and led option mapping initiatives for e-commerce taxonomy projects. I also standardized attributes and validated product variants for automated model training. • Conducted CoT evaluations for LLMs to improve reasoning accuracy. • Ensured safety and alignment by annotating multimodal data. • Led option mapping for e-commerce taxonomy structuring. • Standardized and validated product attributes to enhance model training.
