About luke
I am a detail‑oriented AI prompt engineer and evaluator with advanced English reading and writing skills and extensive hands‑on experience interacting with large language models. Over the last several months, I have designed, refined, and tested prompts to evaluate multi‑turn conversations, identifying reasoning flaws, hallucinations, bias and policy violations. I score responses for clarity, accuracy, tone, and completeness and provide structured written feedback to improve model performance. Previously ranked #1 in North America as a Master Service Consultant for a major automotive brand, I bring proven attention to detail, guideline adherence, and high‑volume productivity. My background in customer‑facing roles sharpened my ability to communicate clearly, translate complex information, and maintain consistency under pressure. I am fluent in English and Vietnamese and passionate about advancing safe, useful AI systems.
