Drawn to intelligent systems, financial infrastructure, research, and building things that matter.

Thinking, lately, about graph intelligence, financial crime, machine learning in finance, building useful things, research that becomes software, and the future of payments.

About

Product, engineering, research, and an enduring curiosity about how things work.

Currently

Financial Technology · AI Research

I'm Iyanu, a product and engineering professional working across artificial intelligence, financial systems, and technology.

My experience spans payments, financial technology, product development, and engineering programme management.

Much of my current research explores how machine learning and graph intelligence can improve financial crime detection.

Outside work, I'm interested in entrepreneurship, books, and understanding how the world works.

Work

Building products and systems at the intersection of technology, finance, and human behaviour.

A selection of organisations and teams I've worked with.

Research

Exploring intelligent systems for financial crime prevention.

My research explores payment behaviour, graph intelligence, explainable AI and real-time risk decisioning. Manuscripts, publications and technical material will be linked as they become available.

01 · MSc spin-off
Manuscript in preparation

Real-Time Behavioural Anomaly Detection for Authorised Push Payment Fraud

Investigating how machine learning can identify anomalous payment behaviour before authorisation, while balancing fraud recall, false alerts and inference latency.

02 · GNN–LLM
Research manuscript

LangGraph-Orchestrated GNN–LLM for Explainable Fraud Detection

Exploring how graph neural networks, language models and agent orchestration can connect suspicious transaction relationships with interpretable investigative evidence.

03 · FCA Digital Sandbox
Planned research

APP Fraud Detection Using Regulatory Sandbox Data

A proposed study of payment fraud detection with sandbox datasets, focused on realistic payment patterns, generalisation and practical deployment constraints.

04 · Mule networks
Planned research

Cross-Channel Money Mule Network Detection

Investigating suspicious flows across bank transfers, electronic money institutions, virtual IBANs and crypto or stablecoin payment channels.

Projects

Ideas become more interesting when you build them.

Research-driven experiments and software exploring how intelligent systems can strengthen financial infrastructure. Explore live applications, research implementations and source code below.

01 / Live Applications
EU payment intelligence · Live research prototype

European Payment Fraud Observatory

An interactive exploration of reported payment fraud across EU member states, payment instruments and time. Built with European Central Bank statistics to examine geographic patterns, fraud rates and historical trends.

Graph intelligence · Prototype

GraphGuard AI

Exploring how connections between accounts and transactions reveal suspicious networks that isolated transaction checks can miss.

Machine learning · Prototype

Fraud Risk Dashboard

An interactive environment for exploring payment behaviour, model decisions and fraud-detection trade-offs through visual analysis.

02 / Research & Engineering
Machine learning · Research implementation

Beyond Binary

Classifying payment fraud risk with machine learning. A research implementation exploring payment statistics, feature engineering, classification models and fraud-risk analysis.

GNN–LLM · Research implementation

Graph-Based Explainable Fraud Detection

An experimental implementation exploring graph neural networks, language models and agent orchestration for explainable fraud detection.

03 / In Development
Risk infrastructure · In development

Sentinel Risk API

A research-driven approach to assessing suspicious payment behaviour before authorisation, with an emphasis on useful decisions and low-latency inference.
