# Fintech Microservices Application
A microservice-based fintech application for managing company identities, processing payments, and handling transactions securely.
## Architecture Overview
The application consists of three main microservices:
1. **Identity Service**: Manages company registration and API credentials
2. **Order Service**: Handles order creation and verification
3. **Payment Processor Service**: Processes payments through different networks
## Features
- Company registration and API key management
- Secure order creation and processing
- Payment processing via web interface or API endpoint
- Transaction routing based on card details
- Order status tracking and updates
- Asynchronous order computation
## Technical Stack
- .NET Core
- PostgreSQL
- Entity Framework Core
- RabbitMQ
- Docker
- Swagger/OpenAPI
- OTEL Collector
- Grafana
- Loki
- Tempo
- Prometheus
## Service Details
