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](https://github.com/fauzanfebrian/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](https://github.com/nextcloud/server/pull/55992)**).
