KELVIN MWENDWA
@kelvinmwendwa
I improve LLMs through RLHF, data annotation, prompt engineering, and quality-focused evaluation.
KenyaWhat I'm looking for
I've worked as a freelance AI Training Specialist for global AI labs through platforms including DataAnnotation.tech, Outlier, and Remotasks, evaluating and refining LLM responses. I create Golden Sets from complex code snippets and creative prose, and rank model outputs for truthfulness, helpfulness, and harmlessness.
Across diverse projects spanning mathematical reasoning and creative writing, I've maintained a 95%+ quality accuracy score. My work includes RLHF, supervised fine-tuning, model ranking, adversarial prompt testing, fact-checking, grammar auditing, and bias detection.
Previously, I annotated large-scale computer vision and NLP datasets, mitigated algorithmic bias in training sets, and provided UI/UX feedback for internal labeling tools. I also use Basic Python for data cleaning and create clear documentation for AI training workflows.
