void-os

An exploratory, from-scratch operating system written in C and C++.

About the Project

Current Status: void-os is currently in its early development stages. It serves as an active learning environment for low-level systems programming and kernel architecture.

void-os is a personal passion project built to demystify the core components that make our hardware function. Rather than relying on existing kernels, I am building this from the ground up to gain hands-on experience with memory management, hardware interrupts, and bare-metal programming.

As a portfolio piece, it demonstrates my ability to tackle highly complex, self-directed engineering challenges, debug without standard libraries, and write highly optimized, hardware-conscious code to future employers.

Technical Overview

Tech Stack

Languages: C (Kernel logic) & C++ (OOP)

Emulator: QEMU for testing

Core Concepts Explored

Bare-metal programming without standard libraries
Direct hardware interaction and register manipulation
Pointers, memory offsets, and custom physical structures
Cross-compilation toolchains and Linker scripts
