This is a repo where I will store many sources sites courses etc that are mostly Free/Freemium some with Premium options, which I consider to be the best in offering us what we need to grow as a programmer, AI engineer, cybersec expert etc (many sources for example hyperskill and Microsoft and Google offer many options, while others are limited to certain preferences such as fullstack web dev and data analysis+databases (ex: FreeCodeCamp or data analysis/ML (ex: Kaggle))
My other course/roadmap githubs or saved hubs (all links lead to other github repos of mine original or forked)
Cybersec: : Cybersecs Roadmap (page link/website in README)
AI/ML (work in progress many links are broken/placeholders): AI ENGINEER ROADMAP Github (page link/website in README)
Free programming books github: Programming books
Project based learning with sources (just another collection of links to other platforms free that give guided projects): Simpler Project based learning
Harder Project based learning (personally) more difficult projects: Advanced Project based learning
Collection of AI ML OD etc projects: AI and ML projects
Collection of free certifications: Free cerifications
These cover multiple areas — web dev, programming, data, CS fundamentals, etc.
