Hey, Myself Jithin working as a DevOps engineer, am currently having the similar process. Since it is a replica I have provided with a lower bid, if interested you can contact back.
Regarding my experience : Totally 7+ years experience in IT industry. Last year for an MNC created the layouts and deployed the stack in AWS. There it was ECS with Fargate. The new project is now is like with EC2, which I mentioned early like this stack seems to be a replica. I can use terraform modules for code reusability and workspace concept for bring if you need more environment without no modification in the existing code, that's the beauty of terraform and I can do it for you.
If interested to know more and to connect feel free to contact back.
Regards,
Jithin Kumar
