Overview

A large-scale insurance application split into independently deployable micro-frontends, enabling multiple teams to build, test, and release in parallel without stepping on each other.

The business problem

A monolithic frontend had become a delivery bottleneck. Every release coupled unrelated teams, regression risk was high, and onboarding was slow.

The solution

I architected a micro-frontend system with a shared shell, federated modules, and a shared design language. Teams own their domains end-to-end and deploy on their own cadence behind a consistent UX.

Architecture

Host shell handling routing, auth, and shared layout.
Module-federated remotes per business domain (quotes, policies, claims).
Shared design system and contract packages to avoid divergence.
Jenkins pipelines per remote with independent deploys.

Engineering decisions

Module Federation for runtime composition over build-time coupling.
A shared, versioned design system as the consistency backbone.
Strict contracts between shell and remotes.

Performance optimizations

Shared vendor chunks to avoid duplicate framework loads.
Lazy-loaded remotes to keep initial load lean.
Independent CI to shrink release lead time.

Challenges

Keeping a consistent UX across independently deployed remotes.
Managing shared dependencies and version skew.
Coordinating auth and state across module boundaries.

Lessons learned

Micro-frontends pay off when team autonomy is the real bottleneck.
Shared contracts and design systems are what keep them coherent.
