Hi HN, I'm working at an early stage startup, and want to learn about concepts and patterns that are crucial for senior roles, like: - Batch Processing - Messaging Queues - Microservices - Design Patterns - Which techniques to apply while working on a task - Properly debugging

Is there any online resource or somewhere I can see this in practice? Or any newsletter, youtube channel that discusses this in detail?

My go to sources are open source repositories where I try to understand the code bases and some PRs. But I feel overwhelmed with the resources.
