LoginFlow Engine

Architecture

Overview

This project establishes a robust backend infrastructure using Google Cloud Platform (GCP), featuring Firestore collections for user registration and application state management.

Backend Containers

User Registration Service

1. Firestore Setup: Created "Reg" and "state" collections to store user registration data and application state, respectively.
2. Dockerized Application: Developed and containerized the application's business logic, deploying it as the "User Registration Service" on Cloud Run.
3. Continuous Integration: Automated the build and push of the Docker image to GCP Artifact Registry.

User Validation Service

4. User Validation Logic: Implemented business logic for user validation, handling edge cases like null email and invalid email forms.
5. Docker Image Build: Constructed and tagged the Docker image, pushing it to GCP Artifact Registry for seamless deployment on Cloud Run.

Session Management Service

6. Session Management: Created a session API for user logout, with corresponding logic and Firestore updates.
7. Container Deployment: Built, tagged, and pushed the Docker image to GCP Artifact Registry, deploying the "Session Management Service" on Cloud Run.

Frontend Deployment

8. Frontend Setup: Established a frontend container built with React, featuring user registration and login pages.
9. Artifact Registry Integration: Developed and pushed the frontend Docker image to GCP Artifact Registry.
10. Cloud Run Deployment: Created and deployed a Cloud Run service for the frontend container, ensuring seamless user interactions.

End-to-End Testing

11. Testing Infrastructure: Defined comprehensive test cases for each backend service, ensuring functionality and reliability.
12. Frontend User Interface Testing: Validated the frontend's user registration and login workflows.

Project Showcase
