Automated Python forensic audit engine designed to detect smurfing, structuring, and ghost-hour risk patterns within Kenyan mobile money transaction logs. 🛡️ Financial Crime Analytics & GRC Enterprise Architecture Welcome to my professional engineering portfolio. This repository serves as a centralized operational hub showcasing data-driven solutions built at the intersection of **Criminology**, **Business Administration** and **Cybersecurity Forensics**. These assets are engineered to tackle localized financial crime typologies, regulatory compliance mandates and infrastructure threat vectors within the East African fintech ecosystem. --- 📊 Core Portfolio Assets 🔹 Asset 1: M-Pesa Automated Fraud Velocity Engine * **Domain:** Financial Crime Analytics / Anti-Money Laundering (AML) * **The Problem:** Threat actors utilize "structuring" (splitting massive illicit fund transfers into minor fragments) and "ghost-hour transactions" to bypass legacy transaction alerts and escape detection. * **The Technical Solution:** Built an automated Python analytics pipeline that ingests transaction ledger streams to instantaneously flag time-delta velocity anomalies and high-value dead-hour movements. * **Core Skills Demonstrated:** Data Analysis, Python Scripting, Transaction Monitoring, AML Typologies. * **File:** `mpesa_fraud_detection_engine.ipynb` 🔹 Asset 2: Enterprise Risk & Compliance Plan (Ongata Rongai Retail Case Study) * **Domain:** Governance, Risk, and Compliance (GRC) / Regulatory Policy * **The Problem:** Mid-sized commercial retail nodes face severe financial exposures from post-transaction M-Pesa reversals, cash skimming, inventory shrinkage, and strict compliance enforcement from the Kenya Revenue Authority (KRA). * **The Governance Solution:** Developed an exhaustive 5-page operational compliance manual integrating a data-driven 5x5 Risk Assessment Matrix, Key Risk Indicators (KRIs), internal control protocols satisfying the **Kenyan Data Protection Act (2019)**, and formal escalation pathways to the Directorate of Criminal Investigations (DCI) and Financial Reporting Centre (FRC). * **Core S …
