At United I designed for pilots, dispatchers, and flight crews, people making decisions at altitude where a slow interface costs more than patience. Their systems are data heavy, so my work was making dense, constantly updating information readable in seconds: Skyplan, which carries a flight from preflight planning through landing, and RPS, where weather, runway performance, alternate airports, and emergency diversions had to resolve fast enough to act on. I helped build a custom design system for both, since off the shelf patterns could not carry that kind of density. I also designed a booking tool that gets crews to their assignments and back home, and joined a small team teaching the broader UX org to test and use AI in their process.
