What is codercat-30-days-30-projects?

CoderCat 30 Days 30 Projects is an open source portfolio building challenge where the creator builds one real project every day for 30 days, all in public. The goal is to give aspiring developers and security learners something tangible to show employers, since as the README puts it, most computer science students graduate with nothing demonstrable to show a recruiter. The projects span four tracks: Python, aimed at backend development and automation roles, cybersecurity, aimed at penetration testing and security analysis, web development, and Java. Each day's work lives in its own folder with code and a short explanation, so anyone can follow along, fork individual projects, or study how each one was built. Tools and technologies listed in the README include Python, BeautifulSoup, Requests, Selenium, and the Telegram Bot API for the Python track, Burp Suite, OWASP tools, Nmap, and the Shodan API for cybersecurity, HTML, CSS, JavaScript, React, and Tailwind CSS for web development, and Java, Spring Boot, and Maven for the Java track. Cybersecurity projects are explicitly labeled for learning purposes only, meant for practice on owned systems or authorized platforms such as HackTheBox and TryHackMe rather than on real targets. The primary language shown on GitHub is HTML, used for web projects, with Python, Java, and other tools mixed in across the different tracks. At the time captured here, the repository was still in early progress, with day one of thirty underway, so the bulk of the promised thirty projects had not yet been published. You would reach for this repo if you want ready made project ideas to build a portfolio, want to learn by following a structured daily challenge, or want code examples across multiple languages and domains that you can freely fork and adapt.
