What I use

The tools behind my work, and what each one is for. Clients don't need to know any of this, but people sometimes ask.

Apple apps

Xcode. Apple's app for building iPhone, iPad, Watch, Mac and Vision Pro apps.
Swift 6 and SwiftUI. The language and screen framework for every new app I write. I still read Objective-C and UIKit for older projects.
SwiftData, Core Data and CloudKit. Saving data on the device and syncing it through iCloud, including sharing between people.
WidgetKit, Live Activities and App Intents. Home Screen widgets, Lock Screen updates and Siri shortcuts.
RealityKit and ARKit. 3D and augmented reality, mainly for Vision Pro.
StoreKit 2. Subscriptions and in-app purchases.

Swift Testing and XCTest. Automated tests that run on every change. My active apps have around 6,250 of them.
os.Logger. Apple's structured logging, set up in every app by feature area, so I can see what happened when something goes wrong.
Instruments. Finding what's slow or using too much memory.
fastlane. Scripts that build the app, take App Store screenshots and upload releases, so shipping is one command.
TestFlight and App Store Connect. Beta builds for clients and testers, and publishing to the App Store.
Git, GitHub and GitHub Actions. Version history for every project, and jobs that run tests or scheduled tasks automatically.

Firebase. Sign-in, real-time databases, cloud functions and crash reports for apps that need a server.
Python. Automation scripts and bots, including the build script for this website and the bot that publishes Belize lottery results on a schedule.
Node.js. Small servers, web tools and scripts.
WordPress. Business websites that owners can update themselves.
HTML, CSS and JavaScript. Hand-built sites when WordPress is more than a project needs.

Claude Code and Cursor. AI coding tools I use to write, review and refactor code faster. Everything they produce still goes through tests and my own review.
AI provider APIs. When an app needs an AI feature, I pick the right provider for the job, or use on-device AI when the data should stay on the phone.

I've used AI on production code since December 2022. It speeds up the work; it doesn't replace testing or judgment.

Tell me what you're trying to build and I'll tell you what it takes.
