About Me

I’m a React Native and Native Mobile Engineer with ~5 years of experience building cross-platform apps and native integrations for Android and iOS.

I work close to the platform layer: designing SDKs, integrating native libraries, and optimizing performance-critical mobile workflows.
My open-source work focuses on JSI, Nitro Modules, Kotlin, Swift, and C++, with practical experience in CMake, Android NDK, JNI, ABI packaging, and native binary integration.

I enjoy solving problems at the intersection of JavaScript runtime and native systems. Recently, my technical deep-dives on React Native background execution and the New Architecture went viral on r/reactnative (16K+ views).

Core Expertise

  • React Native Engineering: New Architecture, TurboModules, JSI, Fabric, Bridgeless
  • Android Native: Kotlin, Java, Android SDK/NDK, Foreground Services, JNI, Gradle, AAR/.so integration
  • iOS Native: Swift, Core Location, Core Motion, PDFKit, CocoaPods, lifecycle/background behavior
  • Native Systems: C++17/20, CMake, prebuilt native binaries, ABI compatibility and packaging
  • App Architecture: scalable cross-platform architecture, performance tuning, API integrations, reliability

3) Production App Engineering

Hands-on experience shipping and maintaining production React Native apps with:

  • Native module integrations (Android/iOS)
  • Background location and lifecycle-sensitive features
  • Authentication and API-heavy workflows
  • Payment gateway integrations
  • Performance and reliability optimization

Open Source Philosophy

I build developer tooling that solves real engineering pain points.

  • Maintainer of independently published React Native libraries
  • npm package release/version management
  • Technical documentation and integration guides
  • Issue triage and developer support

Focus Areas

  • React Native Framework Engineering
  • Native Mobile SDK Development
  • Android Platform + NDK Engineering
  • JSI, TurboModules, Nitro Modules
  • C++ and JNI Integration
  • Native Packaging and Distribution
  • Mobile Performance and Background Systems
