Project Overview

A decentralized, off-grid mobile communication application enabling peer-to-peer messaging without cellular service or Wi-Fi infrastructure by leveraging multi-hop Bluetooth Low Energy mesh topology.

Key Highlights & Architecture

• Constructed a multi-peer mobile mesh client in React Native & Expo using BLE native bridge modules.
• Implemented end-to-end cryptographic message payloads transmitted hop-by-hop across nearby devices.
• Designed an intuitive chat UI with live node discovery and signal strength indicators.
