I lead systems integration, requirements, and verification for complex multi-platform products.

Message

At Charter Communications, I lead systems integration across four platforms, holding 120+ technical baselines under configuration control and turning system capabilities into engineering-ready requirements.

I've closed 65+ UI-to-API permission gaps, strengthening backend access controls, and established PlantUML-based documentation standards adopted across four-plus organizations. I also mentor new hires and offshore partners in systems analysis and reverse engineering.

Previously, I delivered 30+ service enhancements across three engineering layers with zero missed deadlines, built validation tooling for 100+ endpoints, and preserved behavior across 40+ production services during a legacy-to-microservices migration.

My aerospace background includes FAA NextGen deliverables, flight-computer systems engineering, and embedded controls work using MATLAB/Simulink, CAN, ECU calibration, and hardware-in-the-loop validation.
