🎯 Design Patterns in Go

This repository contains my notes, exercises, and implementations from a Udemy course on Design Patterns in Go.
It serves as a structured reference for learning, experimenting, and applying SOLID principles, creational, structural, and behavioral design patterns using the Go programming language.

📝 Extra Tasks

In addition to design patterns, I’ve included some Go practice tasks:

• Random Number Generator
• Merge N Channels
• Number Conveyor
• Worker Pool with Func
• Custom Semaphore with WaitGroup

🚀 How to Use

Clone the repo and navigate into pattern folders to explore the Go examples:

git clone git@github.com:mikebionic/go_course_notes.git
cd go_course_notes/2.Builder/1.stringbuilder
go run main.go

Each folder contains isolated examples that you can run independently.
