CrediYa – Personal Loan Management Platform 🚀

CrediYa is a platform designed to digitize and optimize the management of personal loan applications, eliminating manual and in-person processes. The system allows applicants to enter their data and desired loan information, automates the initial evaluation, and streamlines the administrative management of pre-approved cases.

Key Features ✨

• Loan Product Management: Administrators can create, edit, and delete credit products.
• Application Process: Applicants submit their data and desired loan information.
• Automated Evaluation: The system determines the viability of the application and the applicant's borrowing capacity.
• User and Role Management: Distinct roles for applicants and administrators, each with specific permissions.
• Automatic Notifications: Applicants receive notifications about the status of their loan.
• Performance Reports: Administrators access business performance reports (e.g., total approved loans).
• Efficient and Transparent Experience: Fast and clear process for all users.

Architecture & Methodology 🏗️

• Independent Microservices: Each service is an autonomous component with its own repository.
• Hexagonal Architecture (Clean Architecture): Clear separation between domain, use cases, infrastructure, and application.
• Developed with WebFlux: Reactive, non-blocking APIs.
• Asynchronous Communication: Message queues (SQS) for service integration.
• Databases: RDS for transactional data and DynamoDB for reporting.
• Deployment on AWS: Manual deployment using ECS with Fargate and API Gateway.
• Version Control & CI/CD: Docker and AWS ECR.
• Best Practices: Proper variable naming, constant management, concise methods.
• Code Validation: SonarLint.
• API Documentation: Swagger/OpenAPI.
• Unit Testing: Ensured coverage and quality.
• Gitflow: Each user story (HU) is developed in its own branch.
