EAM Windows-Mobile Sync App

Job ID: 40515680

Budget: $15 – $25 USD

Enterprise Asset Management (EAM) Platform Development Specification

Project Vision

Develop a world-class Enterprise Asset Management (EAM) ecosystem that enables organizations to manage the complete lifecycle of physical assets through a unified Windows Desktop application, synchronized in real time with high-performance mobile applications for iOS and Android.

The platform should be designed using enterprise-grade architecture, modern UI/UX principles, scalable microservice-ready backend patterns, and secure APIs capable of supporting thousands of concurrent users and millions of assets.

The solution should prioritize reliability, maintainability, extensibility, security, and exceptional user experience.

Core Platform Architecture

Design the system using a layered, modular architecture following Clean Architecture and Domain-Driven Design principles.

Recommended stack (or equivalent):

- Windows Desktop: .NET 9 + WPF/WinUI 3 (MVVM)
- Mobile: Flutter (preferred) or React Native
- Backend: ASP.NET Core Web API
- Database: PostgreSQL or SQL Server
- ORM: Entity Framework Core
- Authentication: JWT + Refresh Tokens + OAuth2
- Real-time Engine: SignalR/WebSockets
- File Storage: Azure Blob Storage / AWS S3 / MinIO
- Background Jobs: Hangfire or Quartz.NET
- Caching: Redis
- Logging: Serilog
- Monitoring: OpenTelemetry
- CI/CD: GitHub Actions or Azure DevOps
- Docker support for backend deployment
- Kubernetes-ready architecture

The system must support both cloud-hosted and on-premise deployments with minimal configuration changes.

Development Approach

Deliver the project incrementally through clearly defined milestones:

- Phase 1: Foundation architecture and authentication
- Phase 2: Asset management core
- Phase 3: Maintenance management
- Phase 4: Mobile applications
- Phase 5: Real-time synchronization
- Phase 6: Analytics and reporting
- Phase 7: Inventory management
- Phase 8: Security hardening
- Phase 9: Performance optimization
