Summary
🤩
RockstarSam Scott is a Principal Systems Engineer at Cloudflare and cofounder/former CTO of Oso who blends deep cryptography research with product-focused systems engineering. He holds a PhD with 1500+ citations and publications in four of the top six crypto/security conferences, and has contributed to standards-level work such as TLS 1.3 and the IRTF hashing-to-curve document. A prolific Rust practitioner and fan, he has implemented and refactored core crypto functionality in the widely used ring crate (including RSA-PSS and RSA padding changes). From Rails web apps to low-level cryptography libraries, he focuses on shipping safe, fast, and maintainable systems—recently driving parser and performance improvements that sped up testing and core library performance. Based in Austin, he pairs academic rigor with startup execution to operationalize complex security primitives.
