The original Gang of Four patterns explained with modern Python and TypeScript code. Creational, structural, and behavioral patterns — when to use each, when to skip it, and the real-world codebases where you will see every one of them.
This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on software design patterns and architecture you can find — even without producing a single minute of custom video.
This course is built by people who ship production software systems for a living. It reflects how things actually work on real projects — not how the documentation describes them.
Every day has working code snippets you can paste into your editor and run right now. The emphasis is on understanding what each line does, not memorizing syntax.
Instead of shooting videos that go stale in six months, Precision AI Academy links to the definitive open-source implementations, official documentation, and the best conference talks on the topic.
Each day is designed to finish in about an hour of focused reading plus hands-on work. You can do the whole course over a week of lunch breaks. No calendar commitment, no live classes, no quizzes.
Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.
Factory, Abstract Factory, Builder, Singleton, and Prototype. How each controls object creation, and the problems they solve in codebases with complex initialization logic.
Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy. How to compose objects and classes without tight coupling.
The pattern behind every UI framework, message broker, and reactive library. How to build pub/sub systems that don't leak memory or create circular dependencies.
Replacing conditionals with polymorphism. The Command pattern as the foundation for undo/redo, job queues, and audit logs.
MVC, MVP, MVVM, and the clean architecture concepts that organize large codebases. How frontend frameworks implement these patterns under the hood.
Instead of shooting our own videos, Precision AI Academy links to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.
Practical implementations of all 23 Gang of Four patterns in Python with real use cases.
Modern TypeScript implementations with type annotations that clarify the intent of each pattern.
How MVC became the foundation of web frameworks. Walkthroughs in Django, Rails, and vanilla JS.
Pub/sub, EventEmitter, and reactive programming — how the observer pattern scales from small scripts to distributed systems.
The best way to understand any technology is to read the production-grade implementations that prove it works. These repositories implement patterns from every day of this course.
Every GoF pattern implemented in clean Python with real examples. The canonical reference repo for this course.
Plain-English explanations of every pattern with code examples. The best written reference alongside the GoF book.
TypeScript implementations of all 23 patterns. Useful for comparing typed vs dynamic implementations.
Battle-tested Java implementations used by millions of developers. The go-to reference for enterprise pattern usage.
You keep seeing patterns you recognize but can't name. This course gives you the vocabulary to discuss design decisions precisely.
You need shared vocabulary with your team. This course covers the patterns your engineers already know but may not be applying consistently.
React, Django, and Express all implement these patterns. This course helps you read framework internals with recognition instead of confusion.
