• Refactor existing legacy systems into a microservices architecture to improve system agility and facilitate faster feature deployment.
• Enable easier digitization and maintenance of credit-related processes, including designing credit schedules.
• Enhance system stability and resilience to minimize downtime and operational errors.
• Implement scalable deployment and management mechanisms to reduce operational overhead and improve resource management.
• Standardize monitoring, debugging, and troubleshooting processes for distributed microservices environments.
• Support continuous innovation and rapid adaptation to evolving customer and business needs.

• Design and implementation of individual microservices for core processes such as credit scheduling, customer account management, and transaction processing.
• Robust communication protocols (e.g., message queues, event-driven architecture) among services for reliable data exchange.
• Integration APIs for third-party financial data providers and internal analytics systems.
• Standardized deployment pipelines supporting containerization and orchestration (e.g., Docker, Kubernetes).
• Comprehensive logging, monitoring, and alerting systems to streamline debugging and fault detection.
• Automated scaling and load balancing features to manage fluctuating operational demands.

• External financial data providers for credit assessment
• Internal analytics dashboards for monitoring system health and usage
• Authentication and authorization services
• Payment gateways and banking APIs

• High availability and fault tolerance to ensure 99.9% system uptime
• Scalability to support increasing transaction volumes and user base
• Secure communication protocols and data encryption to ensure compliance and data privacy
• Minimal latency for real-time processing and customer interactions
• Standardized processes for deployment, monitoring, and debugging

The migration to a microservices architecture aims to enable faster innovation cycles, improve platform stability, and support scalable growth. Expected outcomes include a reduction in maintenance and deployment times, enhanced system resilience, and improved customer satisfaction through more responsive and reliable digital financial services.
