Computer science fundamentals provide the essential foundation needed to understand programming, data structures, and algorithms at a professional level. In this category, I write about core concepts, learning strategies, technical problem solving, and the mental models that help developers grow faster and think more clearly.
I am especially interested in helping readers move beyond scattered YouTube tutorials and build a cohesive, "first-principles" understanding that lasts. If you’ve ever felt like your knowledge has "gaps" or you struggle with the logic of complex algorithms during technical challenges, this category is designed to fortify your skills.
Whether you are teaching yourself computer science from scratch, strengthening your algorithmic thinking, or preparing to tackle high-level engineering roles, these guides offer the roadmap. I focus on the "pithy" insights that make difficult concepts click.

Recursion is uncomfortable because it requires trusting that a function works before you have seen it work. Most beginners want to trace every step of execution, and recursive calls multiply those …

I’m going to be honest: math has never been my strong suit. As a systems programmer and algorithmic coder, I often feel like a moron when staring at combinatorics, permutations, or probability. I can …
