FinTech Payment Processing Platform

### Project Overview We partnered with a regional bank to build a **FinTech Payment Processing Platform**. The mission was to create a modern payment gateway that could compete with major international players, offering lower fees and better local support for SMEs in the region. ### Problem Statement Local businesses were paying exorbitant fees to international payment gateways and suffering from slow settlement times. They needed a secure, fast, and locally compliant alternative to accept digital payments. ### Solution Provided NacroSoft engineered a bank-grade secure platform. We implemented rigid security protocols to achieve PCI-DSS Level 1 compliance. The system supports multiple payment methods including credit cards, digital wallets, and direct bank transfers, with a fraud detection engine powered by machine learning. ### Technologies Used * **Frontend:** Angular, RxJS * **Backend:** Java Spring Boot * **Database:** Oracle DB (Transaction Ledger), Cassandra (Logs) * **Security:** HSM (Hardware Security Modules), OAuth 2.0 * **Infrastructure:** Hybrid Cloud (On-premise + AWS) ### Key Features * **Fraud Detection Engine:** ML analysis of transaction patterns to block suspicious activities in milliseconds. * **Multi-Currency Support:** Dynamic currency conversion for cross-border sales. * **Instant Settlements:** Real-time fund transfers to merchant bank accounts. * **Developer API:** Robust, well-documented APIs for easy integration by merchants. * **Tokenization:** Secures sensitive card data by replacing it with unique tokens. ### Business Impact * **Processed $50M+ in transactions** within the first 90 days. * **Reduced fraud incidents by 95%** compared to the bank's legacy system. * **Onboarded 2,500+ local merchants** seeking lower fees and faster payouts. ### Team Size 15 Members ### Role Breakdown * **Security Engineer:** Led the PCI-DSS compliance and encryption strategy. * **Java Architects (2):** Designed the high-availability transaction processing engine. * **Backend Developers (4):** Implemented the core banking logic and external API integrations. * **Frontend Developers (2):** Built the merchant dashboard and analytics reporting. * **QA Engineers (3):** Focused heavily on security penetration testing and load testing. * **Project Manager:** Managed strict regulatory requirements and timelines.
