Mobile App Backend Development

I need a backend built for a mobile app on AWS. We need to use Cognito to authenticate users and OneSignal to handle push notifications. We also need a chat system built for this, ideally using Fargate containers running [login to view URL], there's an aws tutorial we can use as a reference to set it up. We cannot use twilio due to front end restrictions, plus the socket for chat will be used for other in app notifications as well. The database models have also been thought through, so there isn't much design/architecture decisions that will need to be made.

We're looking for this to be done in about 3 weeks.

All the endpoints have the inputs and outputs defined in a swagger file.

Here is a list of the API's I need built in lambda:

GET POST events

GET events/history

GET PATCH DELETE events/{id}

GET POST DELETE events/{id}/join

GET POST events/{id}/changes

POST /events/changes/{id}/accept

POST /events/changes/{id}/vote

GET POST conversations

GET conversation/{id}

POST conversation/{id}/close

POST conversation/{id}/message

GET /users/autocomplete

GET /users/available

GET DELETE friends

GET POST friends/requests

PATCH friends/requests/{id}

POST GET events/invites

PATCH events/invites/{id}
