Challenge

A telecommunications enterprise needed a unified B2B commerce portal across multiple product lines, each with its own legacy frontend. Teams were blocked by shared codebases, conflicting release schedules, and a growing maintenance burden.

Solution

Designed a micro-frontend architecture using Angular module federation, where each product line owned its domain-specific frontend. A shared shell application handled authentication, navigation, and cross-cutting concerns. Defined integration contracts and API gateways to decouple frontend from backend services.

Architecture

• Micro-frontend shell with Angular Module Federation
• Shared design system web components for visual consistency
• API gateway layer for backend decoupling
• Event-driven cross-micro-frontend communication
• Centralized auth (OAuth2 / OpenID Connect) with SSO

Impact

• Enabled 4 product teams to deploy independently
• Reduced cross-team coordination overhead by 70%
• Standardized frontend architecture across the organization
• Decreased onboarding time for new developers from 4 weeks to 1 week
