I assessed AI-generated images for spatial layout, prompt adherence, and visual fidelity using digital image editing tools. I provided feedback on cultural and regional accuracy, particularly for Nigerian contexts in geography, language, and cuisine. My role ensured that visual and contextual details aligned with local standards and expectations. • Graded spatial arrangement and compositional accuracy of images. • Verified prompt adherence and image clarity for LLM-generated visuals. • Provided feedback on regional/cultural alignment (Nigeria/West Africa). • Utilized PixelLab and PicsArt as image evaluation tools.

I graded AI-generated narrative outputs for plot continuity, character consistency, and natural dialogue. This task focused on ensuring long-form storytelling quality within extended context windows for high school and collegiate story settings. Each output was checked for structural coherence and authentic tone. • Evaluated narrative structure and plot logic in multi-chapter outputs. • Assessed character voice, motivation, and thematic consistency. • Flagged off-tone dialogue or unnatural storytelling artifacts. • Graded for educational and narrative engagement quality.

Code Reviewer & Safety Tester | Freelance

Other
I reviewed and evaluated computer code outputs generated by large language models (LLMs) in Python. This involved debugging, optimizing logic, and improving algorithmic efficiency. Targeted Safety Red Teaming was also performed to test the boundaries of models for adherence to defined safety guidelines. • Assessed and rated LLM-generated Python code for logical accuracy. • Identified, flagged, and explained algorithmic inefficiencies and errors. • Conducted targeted safety tests on agentic model logic. • Ensured safe and effective code generation within technical limits.

I evaluated AI model outputs related to math reasoning, fluid mechanics, and applied electricity to ensure academic accuracy and source fidelity. Through Retrieval-Augmented Generation (RAG) tasks, I fact-checked technical content and checked for hallucinations in AI responses. My work included referencing dense technical materials for model validation. • Conducted detailed comparison of AI outputs against source materials. • Flagged inaccuracies and technical hallucinations in LLM responses. • Evaluated referencing/citation integrity for AI-generated answers. • Provided expert STEM validation rooted in Electronics/Computer Engineering knowledge.
