// about me

Building apps people love to use

I'm a Senior Mobile App Engineer with 7+ years of experience delivering production-grade apps across fintech, health, and consumer platforms. I specialize in React Native and Swift, but I'm equally comfortable writing Kotlin for complex native features.

My work sits at the intersection of engineering and product — I care deeply about performance, UX, and the small details that make a great app feel magical.

  • React Native, Swift, Kotlin & Flutter
  • CI/CD pipelines with Fastlane & GitHub Actions
  • Performance profiling & crash-rate reduction
  • Cross-functional collaboration with design & product
