01 / ABOUT
MY APPROACH
Connecting the big picture to the systems behind it.
I have spent my career where technical architecture meets operational reality: developing and evolving systems that support thousands of daily airline activities, continuous data exchange and decisions that need to be right in real time.
From legacy modernization to event-driven integration, from airline operations platforms to graph-based AI, my work combines hands-on engineering, enterprise-scale design, technical leadership and delivery ownership.
Data & AI Solutions
Operational data stores, canonical models, graph neural networks and production AI.
Aviation Operations
Scheduling, flight planning, operations control, NetLine and airline data standards.
Product & Delivery
Roadmaps, solution ownership, vendor evaluation, multidisciplinary teams and execution.
