Summary
🤩
RockstarPeter Ferrie is a Principal Software Engineer with 14 years of professional experience and a deep background in malware research, emulation, and secure execution environments across industry leaders including AWS, Broadcom, Symantec, and Microsoft. He has repeatedly architected intrusion prevention and exploit-detection engines, authored de-compressors and virtual machine emulators, and holds a track record of published research and multiple patents tied to low-level security work. Peter contributes to complex open-source projects such as MAME and a bootstrapped LISP in a boot sector, demonstrating a knack for highly constrained, performance-critical assembly and emulation coding. Based in the Los Angeles area, he pairs hands-on reverse-engineering expertise with systems architecture leadership, mentoring teams to operationalize difficult research into production defenses. Notably, his work spans both historic bootsector/compressor-era reverse engineering and modern cloud-scale secure execution at AWS, a combination that surfaces rare depth across decades of platform and threat evolution.
