About
Hi, I'm Alex - online I'm better known as 0xAX. I'm fascinated by how computers actually work beneath underneath the abstractions we build on top of them: how a machine boots, how the Linux kernel manages memory and processes, and how programs actually run. Systems Inside is where I write it all down.
By day I'm a backend developer at Travelping, building AAA systems for telecom networks on its Cennso platform. In free time, I like taking software apart to understand how it actually works - kernels, runtimes, and the tools we lean on every day.
What Systems Inside is
Systems Inside is the home for my writing - in-depth readings of real source code, hands-on experiments, and practical notes from the low levels of the stack.
Currently it hosts Linux Inside, an in-progress book on kernel internals, and a finished series on x86_64 assembly. More is on the way - the goal is one central place to learn how computers work, from the boot sector up.
