GitHub

GitHub is a cloud-based platform where developers store, share, and collaborate on code projects. Think of it as a combination of Google Drive and social media for programmers – it tracks every change made to code and lets teams work together seamlessly. For career changers, GitHub serves as both a learning tool and a professional portfolio. You can explore open-source projects, contribute to real software, and showcase your coding skills to potential employers. Most tech companies expect candidates to have a GitHub profile, making it essential for anyone entering software development, data science, or related fields.
