Build and ship a cross-platform Installer Application that delivers an offline-first Next.js web UI inside a thin native shell (Capacitor) for iOS 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 + TypeScript) UI in WebView / WKWebView.
• Build and maintain a Capacitor BLE plugin for both iOS & 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 MediaDevices + existing scanner libraries where applicable).
• Build a robust update strategy (bundled UI with optional remote updates guarded by version gates).
• E2E testing on real devices, offline/coverage test scenarios, App Store / Google Play compliance, signing, CI/CD pipelines for both Web and Mobile components.

MUST HAVE:

• Experiencing translating PRD/Requirements into highly scalable, technical design/implementation.
• TypeScript, modern React, ES+, Next.js 14+ (SPA/PWA patterns, routing, Static Site Generation).
• PWA fundamentals: Service Workers, Cache API, offline UX patterns.
• Experience creating layers of abstractions in isolation; SOLID Patterns, etc.
• Capacitor (or equivalent hybrid runtime) and WebView/WKWebView constraints.
• Native mobile development experience iOS (Swift/Obj-C), Android (Kotlin/Java) experience with Bluetooth.
• SCM/Package Managements, Git, Yarn, NPM, Node, etc.
• Preact Signals (or comparable state management patterns suitable for event-driven device telemetry).

STRONG PLUSES:

• Material UI / JSS (or equivalent component/theming systems) and responsive UI design.
• WebSockets and real-time status updates.
• i18n/localization and white-labelling patterns (dynamic branding, multi-region deployment considerations).
• React Native and Mobile release tooling and automation (e.g., Fastlane), store review constraints, privacy disclosures for Bluetooth/camera/location.
• Offline Web storage and sync patterns (Indexed/Watermelon DB), durable queues / retry semantics for “failure queue” workflows.
• Large Monorepo dev workflows, branch integrations, CI/CS collaboration.
