Build a Ktor-Based Backend for a Financial App

Ktor is a Kotlin-based backend framework that ensures high performance, security, data processing, and seamless communication with MongoDB. MongoDB is a NoSQL database that offers flexibility and scalability in storing and retrieving data efficiently. 

In this project, we'll create the backend for a full-stack financial app, FinGenius, using Ktor for the backend and MongoDB for the database. We will also write the documentation for the Swagger UI to integrate with the backend, allowing seamless API testing.
