My Portfolio
FAQ
Why do you use Expo rather than bare React Native?
Expo drastically accelerates deployment speeds, offers robust upgrade pipelines, and ensures reliable cross-platform builds while compiling down to native binaries.
Will the app look identical on both iOS and Android?
Yes. I use responsive design mechanics (NativeWind/Tailwind) to ensure layouts fluidly adapt to different notch geometries, aspect ratios, and screen sizes.
Can you handle hardware features like Bluetooth or Biometrics?
Absolutely. I integrate native Expo modules to safely handle FaceID/TouchID, Camera captures, local storage encryption, and accelerometer metrics.
How do you handle background push notifications?
I configure Expo Notification services or Firebase Cloud Messaging (FCM) to deliver low-latency background notifications straight to your target users.
Can you integrate background geolocation tracking?
Yes. Leveraging my background engineering transit systems like TollGuru, I can build battery-optimized background location hooks.
Will you upload the application to my App Store connect account?
I provide complete assistance setting up Expo Application Services (EAS) pipelines to push production-ready builds directly to TestFlight and Google Play Consoles.
Does the app feature offline operational modes?
I can structure offline-first workflows using local storage solutions like MMKV or SQLite, which securely sync back to your main database when online.
Can you connect the app to an existing backend API?
Yes. I configure type-safe Axios or Fetch managers to cleanly connect with your existing Node.js, Python, Ruby, or Golang backend REST/GraphQL endpoints.
Is source code included in the base packages?
Yes. You receive full access to the complete compiled frontend Git repository upon successful milestone closing.
How do we handle subsequent application updates?
By utilizing Expo's Over-The-Air (OTA) updates feature, we can push layout fixes and code edits directly to users instantly, without waiting for App Store approval.
