Next.js

Next.js application experience at Duffion covers interfaces and the APIs that support them. FULCRUM uses it for retail workflows; Quark uses it for the operator control surface around a separate Python backend.

Choose the boundary deliberately

A shared UI and API repository helps keep changes coordinated, but does not remove the need for validation or versioned contracts. FULCRUM also separates background commerce synchronization into its own service so checkout and integration workloads can be operated independently.

What I build with it

• Custom retail and operational application interfaces
• API routes with explicit authentication and business validation
• Dashboards, data grids, and responsive workflow design
• Integration boundaries between the app and background services

Explore the FULCRUM case study for the implementation behind these capabilities.

Next.js application experience: planning a similar project

An application brief should identify who uses each screen and which work must continue outside a browser request. Retail checkout, background synchronization and operator dashboards have different responsibilities. FULCRUM and Quark illustrate different boundaries around a Next.js interface. Their architecture does not mean every new application needs the same service layout; the workflow determines where those boundaries belong.
