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.
Five apps · one engineer
The work that matters.
A pool roguelike, a wand for your wrist, a trip planner, live emergency alerts and a geography game. All native, all built end-to-end, from design to engineering.
Pool, with a twist.
Eight racks, a score to beat each time, and upgrades between racks — magnet pockets, golden balls, bank vaults. CPU rivals that actually plan their shots, and a new seasonal table every few weeks.

Your Apple Watch is a wand.
Trace one of ten spells with your wrist to trigger HomeKit scenes, dim the lights, or duel a friend. Gesture recognition runs entirely on-device — no accounts, nothing leaves the watch.
