What I'm looking for

I'm looking to build secure, reliable AI applications and ML systems, with opportunities to apply agent evaluation, RAG, multi-agent orchestration, and responsible AI practices to meaningful products.

I've shipped AI agents for Acre Security with 98% accuracy, backed by a custom evaluation system of more than 1,000 human-labeled scenarios for critical security applications.

At Revvity, I led AI/ML projects, established responsible AI governance standards, and integrated RAG, MCP, and multi-agent orchestration into life science product recommendations. I also trained models that improved CRISPR gene-editing prediction by 12% and helped catalog more than 330 million predictions in a searchable database.

I'm continuing to deepen my AI application design and security work through multi-agent systems, red-teaming, and agent-performance benchmarks across analytics, software development, and scientific reasoning.
