Declan · app & security engineer
Security / Web / Apple.
It started with an Apple blog. That pulled me into web development — and web development, once I'd found my first PHP exploit and SQL injection, pulled me into security. Apple won me back for good, and I've been building for its platforms ever since: Swift, Objective-C, SwiftUI & UIKit across iPhone, iPad, Mac, Watch and TV.
