Roofing Ionic Mobile App is a cross-platform field operations application for EH Roofing, built with Angular and Ionic Framework.
Designed as a mobile frontend for roofing service logistics, it integrates with backend APIs for user workflows, crew dispatch, job management, geo tracking, and offline usage. It provides enterprise-grade features tailored to field crews working in variable connectivity.

Tech Stack: Angular 13, Ionic, NgRx, Capacitor/Cordova Plugins, IndexedDB/Storage, REST APIs
- Led architectural design of a modular Angular + Ionic mobile system to support logistics and field operations.
- Implemented robust cross-platform mobile codebase (iOS + Android + Web preview) using Ionic v6 and Angular v13.
- Developed scalable feature separation with routing and lazy-loaded modules for performance and maintainability.
- Designed and extended core platform features:
- Field crew assignment
- Job lifecycle workflows
- Real-time and offline data synchronization
- Secure authentication flows
- Geolocation, mapping, and route visualization
- Integrated native mobile capabilities using Capacitor & Cordova plugins:
- Network status detection
- Unique device identification
- Email composition
- Touch/Face Authentication (biometric support):
- Spearheaded offline-first behavior and queueing mechanisms for mission critical field updates.
- Enhanced build automation and environment management for multi-stage deployments (dev, qa, staging, production).
- Modular Angular architecture with feature modules and shared services.
- NgRx store for predictable state management across complex mobile screens.
- Separation of UI, service, and routing layers for clean maintainability.
- Environment configuration based on deployment target (dev/qa/prod).
- Implemented local persistence via IndexedDB/Capacitor Storage for critical job and form data.
- Built action queueing for offline operations: save locally and sync when connectivity resumes.
- Background worker to detect network transitions and resolve pending operations reliably.
- Designed integration layer for mobile geolocation and route features.
- Abstracted map SDK module enabling:
- Real-time GPS position updates
- Push-pin markers for jobs and waypoints
- Offline map tile caching and route persistence
- Integrated reverse geocoding and geo-fencing for arrival/departure triggers.
(Mapping components assumed implemented or extendable based on enterprise needs)
- @awesome-cordova-plugins for core native access

- Standard Angular CLI + Ionic commands for builds and local serve.
- Multi-target configuration for Android and iOS using Capacitor.
- Environment-specific API keys and secure credential handling.
- Coordinated with backend team for API gateway integration and contract alignment.
- Implemented unit tests using Angular testing tools (Jasmine/Karma).
- End-to-end test scaffolding supporting mobile workflows.
- CI/CD pipeline ready via automated test and build steps.
- Applied lazy loading across modules for faster initial load.
- Used OnPush change detection for high-performance forms and lists.
- Debounced geolocation updates to reduce battery usage and UI churn.
- Throttled sync operations to optimize network utilization.
- Enabled EH Roofing field crews to operate reliably in low-connectivity environments.
- Provided mobile team leaders with visibility into job status and crew progress.
- Reduced data loss and operational friction through offline synchronization logic.
- Delivered a maintainable and scalable mobile platform for future extension.
- Angular and Ionic cross-platform mobile development
- Native mobile plugin integration (Capacitor/Cordova)
- Offline first design and synchronization
