Welcome to JRXNA Base Camp

A Deep Dive into Computer Science

Hi, I'm Joel Rego. My primary fascination lies in Computer Science subjects like Data Structures, Algorithms, Compiler Design, Operating Systems, Databases, and Computer Networks.

Here, I publish my study notes: a repository of my studies, detailed annotations, and tutorial sessions. My aim is to shed light on these topics, and to spark that same fire of curiosity in others that drives my own continued study.
