Build Your Own X (Deep Systems Learning)

This is not a traditional course, it’s a curated collection of project-based systems programming tutorials where you literally build real tools from scratch like databases, compilers, blockchain, operating systems, and even Git.

What makes it powerful is that it forces you into deep understanding of how things work internally, not just using frameworks. Many tutorials are video-based or interactive and come from real engineers.

📚 Build your own AI model, Programming language, Blockchain, Game, Bot, etc.
⏰ Duration: 50–200+ hours (depends on paths you choose)
