ABOUT / ADAM VIAUD
Correctness, Performance, Safety.
I'm an iOS and macOS engineer in Paris, currently building privacy-first infrastructure at Proton VPN. I work in Swift from application architecture down to low-level networking, sandboxed system extensions, binary formats, and performance-sensitive algorithms.
01 / HOW I WORK
Close to the system, in the open.
I'm drawn to APIs that make their constraints visible. Sometimes that's a small, friendly abstraction; sometimes it's noncopyable types, explicit state transitions, or working close to the system calls.
Open source is part of that practice. I landed a cross-platform Data.range(of:) implementation in swift-foundation, and I've contributed to SwiftArgumentParser, VLC for iOS, BlackHole, Ghostty, and Point-Free. My own packages lean the same way — a typestate socket API, a GameController interface in modern Swift, a Core Audio CLI, and an educational Mach-O parser.
I got my start modifying SpringBoard for jailbroken devices; the same curiosity about how the system really works now goes into Mach-O, dyld, and sandboxed IPC. I've talked about LLDB, logging, and virtual machines at CocoaHeads Paris, and I hold a Master's in Computer Science from Paris Diderot.
