Results-driven AI Model Alignment and Evaluation Specialist backed by a Bachelor’s degree with Second Class Upper Division honors with extensive experience training, validating, and auditing frontier Large Language Models and multi-step AI agents. Armed with a strong background across global enterprise platforms, I specialize in Reinforcement Learning from Human Feedback (RLHF), adversarial red-teaming, rigorous rubric grading, and PII compliance. Whether you need precise data annotation, multi-step agent trajectory auditing, technical writing, or localized linguistic accuracy (English, Swahili, and Sheng), I deliver zero-subjectivity, high-precision results under strict quality thresholds. Let’s build smarter, safer digital systems.
