Data Structures & Algorithms
The foundation every great engineer leans on. Learn data structures and algorithms from first principles, so you stop memorizing patterns and actually understand them.
Coding Interview Foundations
Stop grinding random LeetCode problems. Learn the small set of patterns behind almost every coding interview, so the questions start to look familiar instead of impossible.
Python From Scratch
The fastest way from total beginner to writing real Python. Build the fundamentals from scratch and finish with a small project that actually runs, no copy-paste required.
Java for CS Students
The Java your CS course assumes you already know. Learn the language the way college actually teaches it, so lectures and assignments stop feeling like a foreign language.
C++ for CS Students
The C++ the rest of your CS curriculum depends on. Learn pointers, memory, and the STL clearly, so OS, compilers, and interviews stop being a wall.
Object-Oriented Programming
The OOP explanation that finally clicks. Learn classes, inheritance, and design principles by building real examples, so you understand why OOP exists, not just how it works.
Operating Systems Fundamentals
Open up the black box your code runs inside. Learn how processes, memory, and threads actually work, so you stop guessing why programs hang, leak, or crash.
Computer Architecture
What actually happens when your code runs. Go from transistors to cache to assembly, so the machine stops being magic and starts making sense.
Discrete Math for CS
The math your algorithms course assumes you already know. Learn logic, sets, and graphs in plain language, so proofs and analysis stop feeling like another language.
Git & Version Control
Stop being afraid of Git. Learn how it really works under the hood, so commits, rebases, and merge conflicts stop feeling like a coin flip.
