Stack Zero.
I am learning to build computer systems from scratch — all of it documented publicly. No magic. Just learning and code.

Building from zero.

Documenting the process entirely of creating various computer systems from scratch. No starting point or understanding of how things work.

Stack Zero is the public record of that journey. 25 systems. Starting from a shell, ending with a hypervisor. Every step shipped and documented.

Interests span cybersecurity, digital forensics, systems programming, networking and artificial intelligence and self-hosted infrastructure. Everything runs locally where possible.
