About Abhinav Upadhyay
Welcome to Confessions of a Code Addict, where deep dives into computer science meet real-world engineering insights. I'm Abhinav, a systems programmer, compiler enthusiast, and performance optimization nerd who loves exploring how things work under the hood.
This newsletter is for those who enjoy peeling back the layers of abstraction—whether it’s dissecting CPython’s internals, understanding how modern processors execute instructions, or writing a compiler from scratch. My approach is hands-on: I read source code, analyze assembly, and experiment with real-world benchmarks.
What You’ll Find Here
Compilers, Interpreters, and VM Internals – Deep dives into language runtimes, optimizations, and low-level execution models.
Systems Programming & Performance – Understanding branch prediction, caching, memory allocators, and OS internals with practical examples.
