Responsibilities

Build and ship a cross‑platform Installer Application that delivers an offline‑first Next.js web UI inside a thin native shell (Capacitor) for i OS and Android, with native Bluetooth Low Energy (BLE) implemented via a Capacitor plugin. The app must support encrypted local storage, resilient sync/queueing, camera‑based scanning, and integrations with backend services (CTC) and Salesforce.

Implement a hybrid architecture: Capacitor native app hosting a Next.js (React + Type Script) UI in Web View / WKWeb View. Build and maintain a Capacitor BLE plugin for both i OS & Android. Expose stable JS APIs, event listeners, and contracts for device discovery, connectivity, data exchange, RSSI, and proximity workflows. Deliver offline‑first workflows: Service Worker caching, background sync/queueing patterns, durable local persistence of install job records. Encrypted‑at‑rest local data using Web Crypto (and native equivalents where appropriate). Integrate with backend service APIs. Implement camera flows for QR/barcode scanning and job documentation photos (web‑based Media Devices + existing scanner libraries where applicable). Build a robust update strategy (bundled UI with optional remote updates guarded by version gates).

CI/CD pipelines for both Web and Mobile components. Qualifications
