About

I’m Arun Sah, a backend engineer. I’m exploring computing from first principles.

I’m starting with hardware, operating systems, and compilers. The plan is to use that foundation for backend engineering, then AI engineering and research. GPU programming and robotics are also part of what I want to understand.

I call this journey From Computing to Intelligence. This site is where I keep the code, experiments, and explanations. I try to build small things that I can understand well enough to explain.
