Building My Own 64-Bit Operating System Kernel from Scratch

Writing an operating system has always been one of the most challenging goals in software engineering. Instead of relying on existing operating systems, I wanted to understand how a computer works from the moment it powers on until it executes applications. That curiosity led me to build MyKernel, a modular 64-bit operating system kernel for the x86_64 architecture.

The project started with learning the boot process, CPU initialization, and memory management. As development progressed, I implemented components such as virtual memory, process scheduling, inter-process communication, file systems, networking, and device drivers. Every feature required solving low-level engineering problems and understanding how modern operating systems function internally.

Building MyKernel significantly improved my understanding of computer architecture, operating systems, networking, and systems programming. It also taught me how to debug complex problems, design modular software, and work with low-level C and Assembly code.

This project reinforced an important lesson: the best way to learn complex technologies is by building them yourself. Every challenge became an opportunity to gain deeper knowledge and practical experience.

In the future, I plan to continue expanding MyKernel with additional features while exploring cloud computing, MLOps, and production-ready AI systems. My goal is to become a software engineer who can build reliable systems from the kernel to the cloud.

If you're interested in operating systems or systems programming, I'd love to hear your thoughts and connect with other developers working on similar projects.
