Featured Architectures

End-to-end views of modern payment systems

Digital Payments System Blueprint

An end-to-end architectural blueprint for modern digital payment systems, focusing on how banks orchestrate multiple rails, standards, and risk controls into a unified platform.

FocusPayment hub architecture, multi-rail routing, ISO 20022

StackArchitecture diagrams, FRSD-style docs, reference flows

Repo digital-payments-system-blueprint

Models high-value, ACH, RTP, FedNow, and cross-border flows with an emphasis on orchestration and settlement behavior.
Captures real-world concepts from production systems in a vendor-neutral, educational form.
Intended as a learning resource for engineers, architects, and students exploring payments modernization.

AI & Fraud Detection Frameworks

Prototype implementations aligned with research

Federated Fraud Detection Framework

Prototype implementation of federated learning for fraud detection, designed to explore how multiple financial institutions can collaborate on model training without sharing raw transaction data.

FocusPrivacy-preserving fraud detection, collaborative model training

StackPython, ML frameworks, synthetic transaction datasets

Repo fraud-detection-federated

Supports experimental workflows for both batch analytics and near real-time anomaly scoring.
Demonstrates how model updates can be shared across parties while keeping local data private.
Aligns with my published work on federated learning and secure AI in financial systems.

How to Use These Repositories

These projects are intended as reference implementations and learning tools. They are not production systems, but they reflect real-world patterns from Tier-1 banking environments.

Students can use the blueprints to understand how real-time payment systems are structured.
Researchers can build on the AI and federated-learning examples for experimental work.
Practitioners can adapt architectural patterns when designing or modernizing payment platforms.
