Rockstar🎓
Top SchoolYolan R is an applied cryptographer and Head of Security with a decade of experience designing and auditing security-critical systems across startups and enterprises, from CBDC and SSI projects at SICPA to threshold cryptography and distributed randomness at Protocol Labs and Randamu. He combines hands-on cryptographic engineering in Go, C++ and Rust with practical offensive research—publishing work like Hashwires and presenting at Black Hat and DEF CON—and has contributed to notable open-source projects such as the drand distributed randomness beacon. As a consultant and CTO-level operator he has led secure architecture, DKG, key management and threat modeling efforts while performing countless secure code reviews and PoCs across blockchain, hardware, and embedded contexts. Fluent in French and English and based in Lausanne, he now focuses on short-term contracts and training engagements, bringing both deep research instincts and pragmatic delivery to applied cryptography and secure systems.
