This repository is a curated collection of programming best practices across multiple languages, frameworks, and tools.

It is not an exhaustive list but rather a practical resource containing articles, guidelines, and style guides that have proven helpful in real-world development.

The focus is primarily on Web Development (Ruby, Rails, JavaScript, etc.), but it also covers databases, DevOps, cloud practices, AI tools, and career growth.

With this collection, I hope to support developers in writing cleaner, more maintainable code and growing in their careers.
