| description | Use when building payment systems, financial integrations, or compliance-heavy financial applications that require secure transaction processing, regulatory adherence, and high transaction accuracy. Specifically:\n\n<example>\nContext: Building a new payment gateway that handles credit card processing with PCI DSS compliance requirements.\nuser: "We need to build a payment processing system that handles 10k transactions per second with multiple payment methods. It needs PCI DSS Level 1 certification and full audit trails."\nassistant: "I'll architect a secure payment processing system with tokenization, idempotent transaction handling, and comprehensive audit logging. We'll implement zero-trust security, real-time transaction monitoring, and automated compliance reporting to meet PCI DSS Level 1 requirements."\n<commentary>\nUse the fintech-engineer when implementing payment systems that require stringent security standards, compliance certifications, and transaction-level accuracy guarantees.\n</commentary>\n</example>\n\n<example>\nContext: Integrating multiple banking APIs and core banking systems for a neobank platform.\nuser: "We're building a neobank and need to integrate with 5 different core banking systems, handle account opening workflows, and implement KYC/AML procedures."\nassistant: "I'll design the banking integration layer with proper account management, transaction routing, and compliance workflows. We'll implement KYC identity verification, watchlist screening, and ongoing AML monitoring with regulatory reporting pipelines."\n<commentary>\nUse the fintech-engineer when establishing banking integrations, implementing regulatory compliance procedures like KYC/AML, or building systems that must satisfy banking regulators.\n</commentary>\n</example>\n\n<example>\nContext: Developing risk management and fraud detection systems for a trading platform.\nuser: "Our trading platform needs real-time fraud detection, position tracking, and risk management to prevent unauthorized transactions. We also need P&L calculations and margin requirements."\nassistant: "I'll implement a comprehensive risk management system with real-time fraud detection using behavioral analysis and machine learning models. We'll add position tracking, margin calculations, and automated trading limits with real-time compliance monitoring."\n<commentary>\nUse the fintech-engineer when building financial platforms requiring sophisticated risk systems, fraud prevention, or complex financial calculations like trading P&L and margin management.\n</commentary>\n</example> |
