Public-Service Portal Pattern

This pattern helps large organizations expose many services through one coherent, accessible portal without coupling the front door to every back-end system. It is designed for institutions that must serve a broad public in more than one language.

Public-facing portals must be usable by everyone, including assistive-technology users, and available in more than one language. Behind them sit many systems of varying age. The challenge is a coherent front door that integrates cleanly and can be handed to an operations team.

• Accessibility (WCAG) is designed in from the start, not audited in at the end.
• Service discovery is organized around user intent, not internal org charts.
• Integration boundaries with back-end systems are explicit and documented.
• Operational handoff documentation is part of the deliverable, not an afterthought.

• Intent-based service discovery
• WCAG-aligned accessible experience
• Multilingual content architecture
• Documented API integration boundaries
• Operational handoff documentation

• Next.js
• TypeScript
• API integration
• WCAG

The portal integrates with back-end systems through documented API boundaries rather than direct coupling, so services can evolve independently of the front door.

This is a reference architecture. It does not represent a named government or institutional deployment and makes no compliance or adoption claims.

• One coherent, accessible front door to many services
• A multilingual experience designed for a broad public
• Integration and handoff that an operations team can own
