I am an AWS certified Developer Associate. I have good understanding on SQS along with FIFO and Dead letter queue along with the normal queue. I can explain you the SQS in details and able to clarify the doubts if u have any.
What type of queuing system are you looking for??
Can I get the detailed information about the project, like what are you working on, why do you need the queuing system for.
hoping you reply to me soon.
