Selected work

One shared core for four SDKs

// context

VideoSDK ships 4 client SDKs: Android, iOS, Flutter and React Native.

// what I did

Led the move of all 4 onto one shared core.

// result

Android 3.0, iOS 4.0, Flutter 5.0 and React Native 2.0 shipped the same day (Oct 2026).

  • Kotlin
  • JNI/FFI
  • Rust
  • libwebrtc

Android SDK 3.x, Kotlin-first

// context

The 1.x–2.x production SDK was Java.

// what I did

Owned the 3.x major: a Kotlin-only API (227 files, 13.6k lines of Java interop removed), API checks, Dokka docs and the Maven Central release flow.

// result

22 Android SDK releases in 11 months (1.0 → 3.0), 91% of their commits mine.

  • Kotlin
  • Gradle
  • Dokka
  • Maven Central
versions on Maven Central

GPU camera effects, end to end

// what I did

Built auto-framing, low-light and style effects end to end on OpenGL ES + Metal; sole author, shipped in Android 3.0.

// also

Rebranded libwebrtc's JNI layer so VideoSDK runs beside another WebRTC SDK in one app. Fixed a renderer deadlock that froze all remote video.
