A terminal window. An illustrative session runs whoami, which prints: Febri Cahya — Android · Linux · Systems Engineering — Building reliable tools for the layers beneath the interface. Then ls ~/projects lists flux, synthesiscore, hico and ci-build. Location and local time in Indonesia (Asia/Jakarta, WIB), refreshed every 30 minutes by GitHub Actions

~/about

I'm Febri Rahmad Cahya, an independent developer from Indonesia working on the layers beneath the interface: Android system services, Linux, kernels, and the automation that builds and ships them.

I value engineering that is measurable, understandable, and safe to operate: changes that can be explained, verified, and reverted, not tweaks that only look good in a benchmark.

~/now

 current focus · kernel CI
  • Event-driven device state. Following Android system state through binder and framework callbacks instead of polling dumpsys.
  • Kernel work. Android kernels for Xiaomi garnet (5.10 GKI) and lavender (4.4 / 4.19), and the kernel framework behind Zairenkai.
  • Supply-chain safety for root modules. Checksums, pinned signing certificates, and provenance checks for anything that runs as root.
  • Reproducible CI. One shared script layer for GitHub Actions, Harness, and local builds.
An illustrative ci-build run: garnet-gki (5.10 GKI), lavender-4.4 and lavender-4.19 move through resolve, patch, toolchain, compile, AnyKernel3 and release, ending with a kernel image and an AnyKernel3 zip per variant.

~/work

 Flux · SynthesisCore · HiCo Thermal · ci-build A simulated view of Flux: device state flows from the binder monitor, with SynthesisCore as fallback, into fluxd, which applies a profile through flux_profiler while HiCo Thermal follows it. The profile moves from Balance to Performance when a game is in the foreground, to Performance Lite when thermal headroom runs low, and back to Balance when the game exits.
Flux
Adaptive gaming and battery optimization module for rooted Android. A native C++ daemon follows device state over binder and applies coherent Performance, Performance Lite, Balance, and Powersave profiles.
C++ · Magisk, KernelSU, APatch · project site 		SynthesisCore
Event-driven Android system monitor for root daemons. Runs through app_process and publishes foreground app, power, thermal, and battery state to an atomic, inotify-friendly file.
Kotlin · Android 9–17 · used by Flux
HiCo Thermal
A Flux add-on that lifts thermal throttling only while a game runs, then restores the stock thermal stack, with a CPU and battery temperature guard.
Root module · thermal layer · requires Flux 		ci-build
Android kernel CI for the Zairenkai targets. One script layer drives GitHub Actions, Harness, and local builds, and packages each root variant with AnyKernel3.
