when i'm thinking about designing a job queue system, i usually start with the basics.

Hey everyone, I've been thinking about how to set up a solid job queue for doing stuff in the background. You know, like sending out emails, resizing images, or running tasks on a schedule. I've noticed a couple of ways to do this: using services that are already managed like AWS SQS, or building it ourselves using Redis or RabbitMQ. What do you all prefer or find works best? Any particular problems I should watch out for, especially with retries, dead-letter queues, or when things get busy
