What I'm looking for

I seek roles focused on AI prompt engineering, dataset annotation, and ethical model evaluation at mission-driven teams that prioritize quality, collaboration, and measurable model improvements.

I am an AI Prompt Engineer and Annotation Specialist with over three years of hands-on experience designing, testing, and refining high-quality datasets for NLP and multimodal models. I have annotated and verified tens of thousands of data points, achieved consistent 98% QA scores across projects, and reduced annotation errors through prompt tuning and structured evaluation.

I specialize in prompt engineering, bias detection, instruction tuning, and model scoring, and have partnered with industry players such as Appen, Steller, and Telus International. I am passionate about building ethical, user-aligned AI systems and improving LLM outputs through creative prompts and rigorous quality protocols.
