Hi there, I'm eggfly 👋

Mobile & systems engineer and an incorrigible hardware tinkerer.
Android internals · Kotlin / JVM · cross-platform (Flutter · KMP) · Go — plus a growing pile of ESP32 smartwatches and DIY gadgets.

Kotlin Java Flutter Go Python C++ ESP32


🧠 What I work on

  • 🧩 Android runtime & bytecode — hot-fix frameworks, dex/ART instrumentation, and a toy JVM to understand it end-to-end.
  • 📱 Cross-platform apps — Flutter and Kotlin Multiplatform, including native plugin work.
  • 🐹 Go services & SDKs — clean client libraries and small backend tools.
  • ⌚ Embedded & wearables — ESP32 / K210 smartwatches, MicroPython, and DIY hardware.
  • 🛠️ Developer tooling — small, sharp utilities that remove daily friction.
