Hey, I'm Michael

I'm building Promptfoo, an open-source tool for LLM security and evaluation. We help teams red-team their AI systems and catch vulnerabilities before they ship. 200K+ developers use it.

Before this, I was VP of Engineering at Smile ID (identity verification across Africa), and co-founded Arthena and Matroid. Stanford ICME grad, YC alum.

Current Projects

• Promptfoo - LLM red-teaming, evals, and security
• Personal Site - Open-source portfolio template (1000+ forks)

Interests

• AI agents and multi-agent systems
• LLM security and jailbreaks
• Evaluation and observability
• Scaling ML infrastructure
