Micro-Frontend Platform Migration

Overview

Led the migration of a production monolith to a micro-frontend architecture on Webpack 5 Module Federation across 4 product teams, cutting deployment complexity by 40%. Built a CLI that scaffolds a new micro-frontend (port registration, boilerplate and Docker Compose) in under 30 seconds, taking new-team onboarding from 2 days to 15 minutes.

Problem → built → result

Problem

Four product teams shipping from one React monolith.

Built

Module Federation split, plus a CLI that scaffolds a new app in 30 seconds.

Result

Onboarding 2 days → 15 min · −40% deploy complexity

What I built

• Split a production monolith into independently deployable micro-frontends on Webpack 5 Module Federation, with clear code ownership across 4 product teams
• Built a CLI for scaffolding, port registration and Docker Compose wiring: new-team setup dropped from 2 days to 15 minutes
• Cut deployment complexity by 40% by letting each team ship on its own
• Docker containerization per micro-frontend so each team owns its deployment
