Node.js/React.js add "attachments" feature to website app

Job ID: 36628980

Budget: $250 – $750 USD

The app is created and running. There is a messaging feature that sends messages back and forth from tutor to student. We need the messages to include an attachment feature.
It will be limited to .doc, .docx, .pdf, .jpg, .png, .txt, .rtf files
With a size limit of 15MB per attachment (multiple files allowed).
All standard attachment features required should also be included. And files will be stored in an Amazon S3 bucket.
The project repository is on github.
This feature will need to be deployed manually on our AWS Elastic Beanstalk app (no CI/CD pipeline). We will need your help with this so familiarity with AWS is a must.
