What I'm looking for

I'm looking for work where I can improve AI systems through multimodal evaluation, adversarial testing, data quality, and structured feedback while applying my compliance and high-volume operations experience.

At Alignerr and Handshake AI, I train and evaluate multimodal AI systems across audio, text, imagery, visual design, STEM outputs, and adversarial prompting. I audit speech-to-text alignments, build red-team prompts, benchmark model arguments, flag edge cases, and deliver structured feedback that improves model accuracy, safety, and adherence.

My earlier work at McKesson, Vanguard, and Discover Financial Services built my foundation in high-volume operations, compliance, Salesforce CRM, and anomaly detection. I bring consistent quality standards to ambiguous datasets and production workflows.
