About

I am Arun Sah, a backend engineer. I write about backend systems, programming languages, compilers, AI/ML, robotics, and learning technical subjects from first principles.

I am especially interested in understanding computing across layers: CPU architecture, operating systems, compilers, runtimes, distributed systems, machine learning, and robotics.

The long-term direction for this site is simple: a public notebook for learning, explaining, and building from bare metal to intelligence.
