I ship mobile apps, and the agent workflows that help teams ship them.

Shipping apps in teams

Mobile features owned from product discovery to production: native iOS and Android, shared Kotlin Multiplatform and Flutter code, and the services behind them.

My Learning Apps, my own studio since 2016

I founded My Learning Apps Ltd to build educational, accessibility, revision and productivity apps. I own the whole lifecycle: research, design, engineering in Swift, SwiftUI and React Native, release, analytics, marketing and support. Newer apps run AI on the device with Apple Foundation Models, so inference stays private and fast.

See all 20+ apps on the App Store

Four I'd point a developer at, each chosen for a different part of the stack:

Code, with the reasoning behind it

Small, real excerpts from my public repositories, with the problem each one solves and the decision that matters.

@MainActor
@Observable
public final class MapKitSearchModel: MapKitSearchProtocol {

    public var autoCompleteResults: [MKLocalSearchCompletion] = []

    public var searchTerm: String = "" {
        didSet {
            guard searchTerm != oldValue else { return }
            autoComplete()
        }
    }

    func apply(results: [MKLocalSearchCompletion]) {
        // `MKLocalSearchCompleter.cancel()` is best effort. A callback from a
        // query that was just cleared must not repopulate the suggestions.
        guard !searchTerm.trimmingCharacters(in: .whitespacesAndNewlines).isEmpty else { return }
        autoCompleteResults = results
        lastError = nil
    }
}

@main
struct DemoApp: App {
    var body: some Scene {
        WindowGroup {
            ThemeProvider(theme: .editorial()) {
                ContentView()
            }
        }
    }
}

Making coding agents dependable

I ship AI features to production, and I build the tooling that lets engineers use agents without losing rigour: tickets, roles, independent review and fresh test evidence before anything is accepted.

Twenty years in secondary education

Before software I trained as a secondary English and Mathematics teacher and became a senior leader. It's where my educational apps come from, and why mentoring and coaching people through new tools is a big part of how I lead.
