Sep 2024 — Apr 2025
•Developed two major Proof of Concepts (PoCs) focused on configurable interfaces and interactive flight data visualization.
•Built a low-code Flight Information Display System (FIDS) with a drag-and-drop editor, allowing users to design custom screen layouts with components such as flight tables, gate displays, belt information, check-in counters, media widgets, etc. Configurations could be deployed directly to edge devices for real-time display.
•Created a flight-tracking visualization showing aircraft movement and historical flight trails, providing an interactive way to explore live and past flight activity.
•Gained experience in user-focused interface design, data visualization, and building configurable systems for real-world deployments.
