Data Engineering Roadmap

Hi, there! I have built this roadmap with topics that I think that are essential for you to become an awesome data engineer, also, to organize my own studies and fill some gaps that I have identified in myself.

The Roadmap follows an order, the order that I think that's the ideal, however, conider it a suggestion, not mandatory.

Also, I divided the roadmap in three parts:

Essentials
Advanced Topics
Extras (Optional)

Senior Frontend Interview Questions

Some questions about frontend development that might be in your next job interview. The questions were formulated by @mauvieira, a super senior fullstack developer

	# For more information on the compatibility API, see: https://docs.cloud.oracle.com/en-us/iaas/Content/Object/Tasks/s3compatibleapi.htm
	# Keep in mind that for the compatibility API to work, you need to do some extra configuration in your OCI Object Storage Bucket
