About Bertrand

Hello! Passionate iOS developer in the Apple ecosystem, I help you transform your ideas into high-performing and elegant native applications.

Specializing in SwiftUI, I don't just write code: I design products. I am currently working on the complete design of an IoT solution (Hardware + iOS App) involving complex geolocation and Bluetooth communication. This experience allows me to understand the global challenges of your project, beyond simple mobile development.

What I can do for you:
- Native application development (iOS/iPadOS): Creation of modern and fluid interfaces respecting Apple's Human Interface Guidelines.
- Geolocation: Advanced integration of MapKit and CoreLocation (Tracking, routing, geofencing).
- MVP Launch: Have an idea? I help you release a stable and testable first version quickly to validate it with your market.
