About me
Building Native Apps Across Apple's Ecosystem
I'm Pierre — a software engineer with 7+ years of experience shipping native apps across iOS, macOS, tvOS, and visionOS. 5 published apps on the App Store, open-source Swift packages with 100+ GitHub stars, and a cross-platform mindset from day one.
App Store Track Record
Swift and Kotlin are my day-to-day languages. From a custom Keyboard Extension operating within Apple's strict sandboxing model, to a data visualization app shipping on four Apple platforms including visionOS — each project solves a real problem for real users.
What Sets Me Apart
I build apps that are reliable under real usage. Loccali syncs persistent data across devices via iCloud with custom App Intents. Miflas renders animated charts from live government data on four platforms with a shared SwiftUI codebase. My open-source packages — ProgressUI and InfinityScrollKit — are used by hundreds of developers.
Collaboration
I co-developed Amamit — a civic engagement app for Israeli democracy — working alongside a collaborator to ship a SwiftUI + Firebase app from concept to prototype. I value clear communication and fast iteration in cross-functional teams.
Early Adopter of Apple Platforms
I shipped on visionOS within its first year. From SwiftUI and App Intents to StoreKit 2 and Keyboard Extensions — if Apple releases a new framework, I'm already building with it.
How Can I Help?
Whether you're a startup building your first iOS app or an established company expanding to new Apple platforms — let's talk. I specialize in native Swift development from prototype to App Store.
