What I'm looking for

I seek roles where I can improve LLM alignment and model safety through annotation, prompt engineering, and strategic evaluation, collaborating with cross-functional teams in mission-driven organizations.

I am a strategic consultant and AI data trainer with eight years of experience in business analysis, market strategy, and operational modeling. I specialize in annotating and evaluating LLM outputs for accuracy, relevance, and ethical integrity, producing prompts, rubrics, and datasets that improve model alignment and practical performance.

My background includes consulting roles at PwC and independent engagements where I led market research, business-model development, and cross-functional workshops. I combine advanced writing skills, technical tooling (Labelbox, Scale AI, Surge AI), and a focus on model safety to deliver actionable insights and scalable evaluation frameworks for AI systems.
