When Networks Fail, SARA Stands Up: Offline Flood Rescue with Gemma 4 E4B

This is a submission for the Gemma 4 Challenge: Build with Gemma 4

What I Built

During major floods—like the catastrophic 2022 Pakistan Floods that displaced over 33 million people—mobile towers lose power and internet services collapse. This creates a critical communication blackout where stranded victims cannot signal for help, and rescue teams deploy boats, helicopters, and medical assets based on guesswork.

SARA (Safety And Rescue Assistant) is a 100% offline-first, local emergency command center. Deployed on a single coordinator laptop alongside a simple Wi-Fi hotspot, it creates a private local network—no internet required.
