Freelancer Overview

As an Electrical and Electronics Engineering graduate (Second Class Upper) from the University of Ibadan, I bring strong domain expertise in STEM fields that directly supports high-quality AI training. My engineering background covers power systems, control systems, signal processing, circuit design, and engineering mathematics — areas where I can evaluate AI-generated content for genuine technical accuracy rather than surface-level plausibility. I have hands-on experience producing precise technical documentation, conducting systematic analysis, and applying structured logical reasoning through two engineering internships where accuracy and attention to detail were non-negotiable. What sets me apart from general annotators is my technical depth. I can review MATLAB and Python code for correctness, evaluate step-by-step engineering reasoning for logical errors, identify hallucinations in AI responses about STEM topics, and generate high-quality technical question-and-answer pairs for training datasets. I also built an AI-integrated hardware project during my degree — a smart pill dispenser with AI-based verification logic — giving me direct exposure to how AI decision systems work in practice. I am a native English speaker, comfortable working independently in remote asynchronous environments, and committed to maintaining high accuracy across every task I take on.

Freelance AI Trainer & Data Annotator – STEM/Engineering Domains

Text
As an independent AI Trainer and Data Annotator, I specialize in evaluating AI outputs and annotating STEM-focused data. My work involves reviewing technical engineering and mathematics content, assessing code correctness, and verifying AI-generated problem solutions. I handle tasks such as content categorization, LLM evaluation, red teaming, and hallucination detection across engineering and mathematics domains. • Evaluated LLM responses for accuracy, helpfulness, reasoning, and instruction-following in STEM domains. • Annotated and categorized technical engineering and mathematics texts with high precision. • Reviewed and rated code outputs and mathematical reasoning for quality, correctness, and efficiency. • Conducted technical QA, generated questions, and performed preference ranking for AI model improvement.
