Real World Design Patterns

• 🇮🇹

This repository is a collection of useful design patterns implemented in industry-requested languages: Go, TypeScript, and Python.

Forget abstract Foo and Bar examples. Every pattern here is demonstrated with a realistic, practical use case—the kind of code you might actually find in a professional codebase. The goal is to bridge the gap between academic theory and real-world application.

For each pattern, you can also find a link to a TikTok and YouTube video where I explain it step-by-step.

Features

• Industry-Relevant Languages: Clean, idiomatic implementations in Go, TypeScript, and Python.
• Realistic Examples: Code that solves concrete, real-world problems.
• Video Explanations: Each pattern comes with a step-by-step video guide to help you understand it better.
