Overview

Pebblebee is a Bluetooth item-tracking platform that helps users find anything, anytime, from any device. As the Lead iOS Engineer, I took ownership of the app’s technical direction, team structure, and code quality — ultimately driving the App Store rating from 2.4 to 4.6.

My Role

  • Core Location services and Bluetooth (BLE) integration
  • iBeacon ranging for proximity-based tracking
  • Subscription management via StoreKit
  • Push notifications and Firebase Analytics
  • Migrated from RxSwift to Combine
  • Transitioned UI layer from UIKit to SwiftUI

Impact

  • App Store rating: 2.4 → 4.6 after taking over iOS development
  • Successfully replaced outsourced team with in-house engineers
  • Mentored and grew a high-performing iOS team
