Core Banking System

The architecture of the Core Banking system was designed as a high-performance, multi-tenant ecosystem, capable of hosting multiple financial entities on a single, secure infrastructure. At its heart, I engineered a robust RESTful API that serves as the backbone for both the mobile banking application and the comprehensive administrative backoffice. This core manages the entire customer lifecycle, integrating sophisticated KYC and Compliance modules to meet regulatory standards, while maintaining a flexible multi-currency wallet system with support for "pockets" to help users organize and save their funds effectively.

To power the financial logic, I developed an advanced credit engine that automates risk assessment and loan distribution based on real-time data. The system handles complex ledger operations with ACID compliance, ensuring that every transaction across wallets and accounts is atomic and immutable. On the security front, I implemented multi-factor authentication (MFA), end-to-end encryption for sensitive data at rest and in transit, and advanced rate-limiting to protect the API from malicious actors, ensuring the platform is as resilient as it is functional.

The user experience was completed with a high-end mobile application designed for seamless financial management, allowing users to move funds, manage cards, and track spending in real-time. Simultaneously, I built a centralized administrative suite that gives operators full visibility into system health, liquidity pools, and user activity. By combining advanced caching layers for speed with a distributed microservices approach, I delivered a banking solution that is not only highly scalable and secure but also provides a modern, intuitive experience for both the end-user and the institution.
