Free Wortley is a security-focused engineering leader with 12 years of experience building secure systems at scale, currently shaping security architecture for AI at Scale AI. He founded and led LunaSec (YC S19), raising VC funding and shipping open-source tooling that helps detect critical vulnerabilities like Log4Shell—a term he coined in a viral blog post. His background spans hands-on product security roles at Figma, Uber, and Snap, plus deep engineering experience building backend SDKs and deployment pipelines in TypeScript. He blends founder-level product instincts with programmatic security practices, from AppSec and network controls to data and AI security for Snowflake-scale systems. Free also brings a long-standing indie-dev pedigree—shipping MMORPG infrastructure and custom engines—which informs his pragmatic, performance-minded approach to architecture. Based in Seattle, he pairs hacker curiosity with proven startup execution to turn security research into operational safeguards.
