maigrate flutter application from firebase to aws -- 2

Hi there! I'm looking for an expert to help me migrate my existing Flutter mobile application from Firebase to AWS. I've been using Firebase for my current backend technology, but I'm now ready to scale up and explore the possibilities of AWS for this project. AWS Amplify and AWS Lambda would be great, but I'm open to any suggestions. The project needs to be completed within a month, but I'm flexible if needed. I'm sure that together, we can make this project a success!
