What I'm looking for

I'm looking to apply my airline operations, crew planning, and aviation finance background to improve regulatory compliance, staffing, operational reliability, and crew cost performance.

At Global Crossing Airlines, I lead crew planning across five operational bases and approximately 300 crew members, combining operational coverage, FAA compliance, and cost control. I built forecasting models and dashboards for flight hours, training, lodging, per diem, overtime, and staffing decisions.

I've helped reduce annual day-off pay costs from about $3 million to $1 million through scheduling and travel optimizations. My background spans crew scheduling, operations control, aviation finance, and frontline inflight operations, giving me a practical view of reliable airline operations.
