Legacy Multi-Agency Intelligence Platform Modernization
Capstone Legacy System Modernization. Began as my graduate capstone in Fall 2024 and continued as a Graduate Research Assistant in Spring 2025. Inherited a nonfunctional multi-agency intelligence platform built for an industry partner and completed its end-to-end modernization. Migrated the backend from .NET 5 to .NET 9, replaced obsolete dependencies, and rebuilt failing components. Replaced the platform's paid mapping service with a real-time mapping layer built on Google Maps API, SignalR, and Hangfire, and added the security layer it had never had: Azure AD OAuth2, TLS, field-level encryption, RBAC, audit logging, and anomaly detection. Deployed the recovered system to Microsoft Azure.
