Security Architect · Systems Designer
A career at the intersection
of hardware, software, and trust.
Designed and built the entire software stack for a distributed real-time telephony platform handling 30 lines per T1 trunk — 1,500 simultaneous lines per site, across 11 countries in Europe, with multiple sites per country. Signals arrived via dedicated hardware termination boards with DTMF detection per line, routed through the NeXTSTATION's DSPs. Operators in centralised facilities monitored and intervened on live calls over 64kbit DSL links split between voice and data. Built entirely in Objective-C with a team of three to five. The system ran live at scale across a continent.
Sole architect of Apple's security foundation across every surface — from the first Keychain implementation in OS X through the hardware roots of trust that defined how a billion devices boot, authenticate, and update. Designed the secure boot chain that became the foundation of iOS. Architected manufacturing security for every Apple device ever built. Created over-the-air update security without on-device fuses — a novel anti-replay architecture that remains in production today.
Led data, analytics, and security architecture for a next-generation electric vehicle platform. Pioneered the intersection of real-time security and functional safety — two disciplines that had never been required to coexist at the architecture level. In automotive systems, a security failure and a safety failure are the same failure. Designing for both simultaneously, without sacrificing either, required building something new.
Core security architect on AROS — Meta's operating system research project. Brought hardware security architecture discipline to one of the world's largest infrastructure organisations.
Worked directly on the core AArch64 security architecture — the instruction set powering virtually every mobile device and a growing share of servers on the planet. Domain covered the full embedded ecosystem: anything with a screen or HDMI port. Smart TVs, set-top boxes, SoCs, DRM architectures for the streaming industry, component vendors, and the OEMs building on top of them. A front-row view of why fragmented supply chains produce fragmented security — and what it takes to hold an ecosystem together at the silicon level.
Led the global rollout of BlueCruise — Ford's hands-free highway driving system — across the F-150 and Mustang Mach-E. Responsible for the data, analytics, and technology architecture underpinning one of the largest autonomous driving deployments in the industry. Security architecture for connected vehicle systems at global scale.
Security is not a feature.
It is the condition
under which everything
else is possible.
For a long time, the industry treated security as the hardest problem.
It isn’t.
The hardest problem is building systems that are secure, safe, reliable, and correct — simultaneously, without compromise. That problem has never been solved… yet.
