Rockstar🎓
Top SchoolHayden Roche is a Staff Firmware Engineer based in Barcelona with 11 years of experience building low-level systems in C and C++ across embedded devices, cryptography, and high-frequency trading. He currently develops firmware for the Blues Notecard, turning physical products into data-driven services, and previously led firmware and security work at wolfSSL where he ported numerous open-source projects to use wolfSSL as a TLS/crypto backend. His background includes designing FPGA-based ultra-low-latency components at IMC and delivering signal-processing pipelines at MIT Lincoln Laboratory, giving him rare cross-domain fluency in hardware, FPGA toolchains, and networking protocols. Hayden is comfortable acting as a technical liaison to customers on FIPS and crypto matters and regularly uses gdb and Wireshark to debug complex systems. He has contributed fixes and security improvements to the widely used wolfSSL library, including OCSP ASN code and MSVC compatibility, demonstrating attention to portability and secure defaults. Colleagues know him for turning protocol and compliance constraints into pragmatic, production-ready firmware.
