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.
