Summary
👤
Senior🎓
Top SchoolGus Narea is a software engineer with 17 years of experience building resilient, security-focused systems and protocols, currently working at Defakto Security in the UK. He has spent the latter half of his career designing and implementing cryptographic and networking protocols, and founded Relaycorp to deliver censorship-resistant communications—raising and managing over $750k to build the Awala network and related products. Gus has production-scale authentication experience from Auth0, where he helped run the Authentication API handling tens of millions of logins daily and led a major Node.js upgrade across cloud and on-premise environments. He contributes to open source cryptography tooling, including enhancements to the pure-JavaScript PKI.js library for CMS/PKCS#7 EnvelopedData handling and ECDH key flows. Comfortable from protocol design to cloud-native deployment, he blends rigorous security thinking with pragmatic engineering and a history of passing independent security audits with no major findings. An Oxford-trained software engineer, he often pairs research-grade protocol work with hands-on implementation across TypeScript, Kotlin, Node.js and cloud platforms.
