Freelancer Overview

I am an experienced AI Trainer and Data Annotation Specialist with a strong background in training, evaluating, and refining AI models for leading organizations such as xAI, Invisible, Erud AI, and Micro1. My work spans RLHF scoring, SFT prompt and response writing, multimodal annotation (text, audio, image), and rigorous dataset quality assurance. I have contributed to projects involving natural language processing, reasoning, dialogue, sentiment analysis, and classification, consistently ensuring high standards for accuracy, consistency, and ethical alignment. My attention to detail, ability to identify biases and inconsistencies, and experience with annotation platforms and QA tools enable me to deliver high-quality datasets that drive model improvement and robust AI performance. I am also proficient in English, Swahili, and Oromo, which allows me to support multilingual data projects and culturally appropriate evaluations.
