01 / The product context
A workflow that reaches beyond one screen.
Security operations span people, sites, shifts and incidents. An officer needs practical tools while on duty; the management team needs a broader view of the same operation. This project demonstrates how mobile and web experiences can serve different responsibilities while working with shared records and workflows.
03 / Engineering considerations
The connections
matter as much
as the screens.
A shared backend, different interfaces
Flutter handles the mobile experience, while Next.js provides the web workspace. A Node.js/Express backend and PostgreSQL data layer connect the applications. This separates interface needs while keeping business rules and records in a shared system.
Mobile work needs device capabilities
Location, camera and scanning workflows require device permissions and practical failure states. They are part of the product scope and testing plan, not details to postpone until after the screens have been designed.
Roles shape the product
Officers, team leaders and administrators need different levels of context and access. The application structure reflects those differences across mobile and web. A comparable project starts by mapping responsibilities and who can perform each action.
