A working catalogue of native iOS apps I’ve shipped as IC, tech lead, and architect, from indie launches to the App Store’s largest catalogues. Hover any tile for the role, stack, and scale.
AR was a side quest at first: branded experiences for Walmart and Nat Geo. Now it’s central. I’ve shipped XR features inside the Disney and Nordstrom apps, taken first place at MIT’s Reality Hack, and spend the off-hours pushing visionOS.
Led the integration of an AR immersive experience aboard Disney's newest cruise ship, wrangling Unity-built game features into a native Swift iOS app, with location-aware triggers across the ship's decks.
Multiple consumer-facing XR experiences shipped inside the Nordstrom apps, moving the bar for what's expected of a fashion retail iOS app.
Branded VR shopping experience for Walmart, built at Mutual Mobile to create memorable in-store touchpoints.
An interactive VR experience for Nestlé KitKat: guests pointed at virtual flavor blasters to shoot ingredient selections onto an oversized digital bar and design their own KitKat in real time. Built for in-store and experiential marketing activations as a showcase of VR for brand interaction and product personalization.
Nat Geo Shared AR Cave Exploration: guests explore a prehistoric cave, as a multiplayer experience, guided by a Neanderthal.
Ongoing work in RealityKit, Reality Composer Pro, and Unity PolySpatial, testing spatial-first interaction patterns before they’re convention.
Took 1st in Mobile AR and Best Engineering Hack at MIT Reality Hack 2018, a shared-world multiplayer ARKit framework before Apple shipped one.
Integrated Disney's MagicBand+ wearable into the Cruise Line Navigator, seamless handoff between phone, band, and physical onboard experiences.
A mix of reference architectures and small experiments I keep public: app-architecture samples (FOAA, TCA), RealityKit math helpers, Metal shader playgrounds, and algorithm demos.
An Xcode Playground file for experimenting with Metal Shaders.
Example project demonstrating the use of Adjacency Lists to manage an undirected graph of friends.
RealityKit 3D vector helper functions.
Production Claude Code workflow: hook-driven skill activation, automated quality checks, dev-docs planning loop.
Sample codebase demonstrating Feature Oriented Application Architecture (FOAA).
Sample codebase demonstrating Swift Composable Architecture (TCA).
A working engineer's guide to iOS apps that survive contact with real users, teams, and time. Patterns from 16 years at Disney, Nordstrom, Schwab, and YouVersion: offline-first sync, feature-flagging, modular SPM, and Swift Concurrency migration. Companion repo to Built2Last.
Opinionated test setup using Swift Testing, snapshot Previews, and the agile testing pyramid as scaffolding.
One book, written from the keyboard of a working iOS engineer, for the next one.
The traits that make a good engineer, patience, a bias to finishing, comfort with mechanical detail, don’t only show up in source. A few side-builds that exercise the same muscles.
Built from scratch: vintage arcade hardware fused with a working kegerator. A multi-month exercise in mechanical fabrication, electronics, and refinishing. Now a fixture in the home.
A gas-free lawn-care trailer to house my absurd collection of EGO lawn care equipment, including a fleet of EGO battery banks, recharged from a solar array, so a full route runs on sunlight instead of fuel.
Talks, awards, and formal credentials.
