Learn C++.
Build Real Systems. Prove You Can.

A structured, project-based C++ course for engineering students who want to write firmware, build tools, and join the 5% who actually ship real systems. Built for Nigerian and African engineers.

Engineers who skip this course don't build better things — they build nothing. The version of you that ships firmware, writes robotics code, and lands a systems role is on the other side of this course. That version of you isn't optional. Start now.

Learning Progression

Six phases. One destination.

This is not a playlist. It is a ladder. Each rung is earned. Each phase unlocks the next. Engineers who skip rungs fall. Engineers who climb reach the top.

Inspired by Real Production Code

Projects from real systems.

Every project in this course is inspired by patterns extracted from real-world C++ codebases — adapted into teachable milestones. These are the kind of things working engineers actually build.

Phase 2 · Practice
Minimal Text Tokenizer
Parse input text into tokens using character classification and string traversal. The same pattern used in real compiler lexers and language model tokenizers.
Inspired by: llama.cpp · ggerganov

Phase 3 · Integration
Pixel Value Analyzer
Load raw image data, compute channel statistics, detect regions above brightness thresholds. The foundational operation behind every computer vision pipeline.
Inspired by: opencv/opencv · Intel

Phase 3 · Integration
Audio Frame Buffer Processor
Implement a circular buffer that processes audio frames: compute RMS energy, detect silence, and log frame events. The exact pattern in whisper.cpp's audio pipeline.

Phase 4 · Real-world Systems
Key-Value Store
Build a file-backed key-value store: insert, lookup, delete, persist to disk. The same data structure pattern powering RocksDB and LevelDB at Facebook and Google.

Phase 4 · Real-world Systems
JSON Config Parser
Build a lightweight JSON-like config file parser from scratch: tokenize, parse key-value pairs, support nested objects. Same concept behind nlohmann::json, the most-starred C++ library.
Inspired by: nlohmann/json

Phase 5 · Portfolio
Nearest-Neighbor Search Engine
Implement brute-force vector similarity search over a small dataset. The foundational algorithm behind FAISS — Facebook's billion-scale similarity search library.
