GitHub Repositories Every Software Engineer Should Know
Finally, after a long time, I am realizing my desire to write articles to help other software engineers advance their careers. With this, I intend to help them improve their knowledge while allowing myself to learn and grow during the process.
In my first article, I present to you a compilation of interesting repositories for all software engineers who seek to stay updated and improve their skills whenever possible, regardless of their level or position.
Let's get straight to it, organized by categories:
- RoadMaps
- Books, Blogs, and Websites
- Algorithms
- Design Patterns
- System Design
- Design Resources
- Projects, Tutorials, and APIs
- Interviews
RoadMaps
In the RoadMaps category, we have two repositories that provide a pathway to follow when you are looking to learn about a language or tool, giving you a direction on the basic knowledge you should acquire or already have.
Interactive roadmaps, guides and other educational content to help developers grow in their careers.
Community driven roadmaps, articles and resources for developers
Roadmaps are now interactive, you can click the nodes to read more about the topics.
Here is the list of available roadmaps with more being actively worked upon.
Have a look at the get started page that might help you pick up a path.

Introduction
Design patterns are solutions to recurring problems; guidelines on how to tackle certain problems. They are not classes, packages or libraries that you can plug into your application and wait for the magic to happen. These are, rather, guidelines on how to tackle certain problems in certain situations.
