Lead Mobile Developer at Flight Pro International, building Flutter aviation apps and Kotlin airport display systems.

United States

Message

At Flight Pro International, I developed a cross-platform Flutter app for commercial aviation travel and operations, with real-time flight updates, digital documents, and manifest management. I also built a native Kotlin and Jetpack Compose airport display app for live facility maps and flight boards.

At L&T Technologies Services (LTTS), I led mobile application work across projects including a Flutter app for Bluetooth-enabled lighting and the Green Commune sustainability platform. For Carrier’s Equip Touch, I developed the project architecture and a reusable npm plugin for exchanging data with controllers over BACnet.

Earlier, I developed Android and cross-platform apps for connected devices, including BLE sensor monitoring, USB-connected tools, and an aquarium control system. My work has also included Xamarin, React Native, Kotlin, and Flutter, as well as mobile application architecture and release.
