Rockstar🎓
Top SchoolMike Lodder is a software engineer and security-focused polyglot with a decade of experience designing and implementing cryptographic systems, secure protocols, and privacy-preserving architectures. Based in Salt Lake City, he blends hands-on R&D—implementing crypto primitives, migrating secure wallets to SQLCipher, and hardening Hyperledger and Indy components—with practical DevOpSec and CISO-level responsibilities. A Rust expert and active open-source contributor, his work includes substantive contributions to well-known projects like Hyperledger Ursa and cryptography libraries used by Coinbase, demonstrating deep protocol and interoperability expertise. He’s an advocate for self-sovereign identity and privacy, has helped develop decentralized key management and a DHS protocol, and enjoys coaching teams to adopt rigorous security best practices.
