What I use day to day.
I've used so many tools that I can't name them all here. I think the point is very much that you can learn something fast rather than have worked with something specifically. Nevertheless, I do have tools I prefer. I am not mentioning platforms and tools like Github, Git, Docker and so on (this should be obvious).
Cloud
AWS
I use more of the core AWS services like Lambda, API Gateway, ECR, ECS, S3, Route 53, etc.
GCP
I use everything I don't like from AWS, such as BigQuery.
