Valar Dohaeris; I'm Fauzan. Software Engineer.

Currently banging my head against the kernel until it makes sense.

I solve problems with code, mostly because I caused them in the first place.

By day, I build scalable enterprise infrastructure and cloud-native systems. By night, I abandon high-level abstractions to break things closer to the metal. I do not believe in magic code. I believe in understanding the pointer arithmetic behind it.


🧠 Active Processes

Bridging the gap between "It works" and "I know why it works." I’ve centralized my documentation in the Engineering Journey monorepo, mapping the stack from logic gates to cloud infrastructure.

  • Layer 1: The Hardware (Nand2Tetris): Demystifying the CPU. Built an assembler and VM translator to understand exactly how code becomes electricity.
  • Layer 2: The Kernel (XV6 & Linux): The playground. Successfully recreated Go routines in C using RISC-V pipe syscalls and wrote my first Linux kernel module.
  • Layer 3: The Application (C & Open Source): Mastering manual memory management and contributing to the real world (Merged PR for Nextcloud Server).

🛠️ The Tools
