JRXNA Base

Learn. Code. Share. Repeat.

I'm Joel Rego. My primary fascination lies in core CS subjects like Data Structures, Algorithms, Compiler Design, Operating Systems, Databases, and Computer Networks. I'm a lifelong student and I am still figuring things out.

This is a repository of the things I'm learning. JRXNA Academy is where I document my deep dives into CS fundamentals. JRXNA Stream is where I think out loud about study techniques. JRXNA Notes is where I write down random insights.
