Backend Assignment-User Document Storage Service

Create a REST API to search and download the file in a user storage account
-- Files are stored in an S3 (Only On s3 bucket)

Input
Username: “sandy”
Search File Name Term: “logistics”
1. Search Files - Mandatory to attempt
2. Upload Files -> Optional (You can write an API for upload as well)
Each user would be maintained as a folder. Search for the user would only search his folder in
S3
1. No Authentication
2. Files are stored in an S3 bucket for each user - ( S3 Integration )
3. Single s3 bucket as storage
4. Search on Filename only
5. Optimized APIs calls
6. Design for Extensibility

Things to take care of
1. No UI - REST Compliance APIs only
2. Testable by Postman/Swagger (No UI)
3. Will prefer code structured in proper fashion
4. Will prefer JUnit
5. Using any Java Framework ( spring boot, dropwizard etc)
