Sample Experience Bullets

• Served as lead developer on a fintech mobile app with 1.2M downloads and a 4.8-star App Store rating that processes over $50M in monthly transactions. Worked across both iOS and Android codebases and coordinated releases with the backend team on a bi-weekly cadence
• Got the crash-free rate from 97.9% to 99.7% by adding structured error handling, fixing 40+ null pointer issues, and setting up Firebase Crashlytics dashboards that the whole team monitors daily. App Store reviews mentioning crashes dropped to near zero
• Built an offline-first architecture using Core Data for local persistence and a background sync queue so the app works fully even with spotty connectivity. Field workers in rural areas reported being able to complete their tasks without worrying about cell coverage
• Cut app startup time from 3.2 seconds to 1.1 seconds through lazy loading of non-critical modules, compressing bundled assets, and restructuring the dependency injection graph. The improvement was especially noticeable on older devices that make up about 30% of our user base
• Added Face ID and Touch ID authentication plus end-to-end encryption for health data stored on the device and in transit. The implementation passed a third-party HIPAA compliance review on the first attempt with no findings
• Published builds to the App Store and Google Play every two weeks using Fastlane for automated signing, building, and uploading. Managed beta testing through TestFlight and internal distribution channels with about 200 beta testers giving regular feedback
• Worked with the backend team to co-design the REST API contract for 15+ endpoints used by both iOS and Android apps, including pagination, error response formats, and authentication flows. The shared contract reduced integration bugs by about 70%
• Wrote SwiftUI views for the new onboarding flow that replaced the old UIKit implementation with smoother animations and a more modern look. Onboarding completion rate went from 68% to 82% and users rated the new flow significantly higher in surveys
• Handled push notification delivery through Firebase Cloud Messaging with deep linking support for 8 different notification types. Notification tap-through rates averaged 12%, which was about double what the product team expected based on industry benchmarks
• Implemented a custom analytics framework that batches events locally and sends them in compressed payloads to reduce network usage by about 60%. The framework tracks 50+ event types across both platforms with consistent naming conventions
• Built a reusable component library in SwiftUI with 30+ UI components including custom charts, form inputs, and loading states that the team uses across 4 different app modules. The library reduced repetitive UI code by roughly 40%
