Nowadays software development is a challenging task as the number of programming languages, frameworks, libraries are increasing rapidly day by day. Luckily, the number of resources to learn on the internet for free also increased a lot. There are a ton of free resources to learn almost everything on the internet. There are lots of official documentation, blog posts, Udemy courses, YouTube videos etc.

As a backend developer who primarily work on JVM based languages/frameworks like Java, Kotlin, SpringBoot etc, following are a collection of resources I usually follow to learn new things. Thought of sharing with you, it could be helpful for you too.
