Overview

Led the end-to-end migration of a production monolith to a micro-frontend architecture using Webpack 5 Module Federation across 4 product teams. Designed CLI tooling for scaffolding, port registration, and Docker containerization — reducing new MFE setup from 2 days to 15 minutes. Implemented module-sharing strategies that cut bundle size by 30% and enabled zero-downtime rollout for each team.

Implementation Highlights

  • Modernized a production monolith into scalable micro-frontends using Webpack 5 Module Federation, improving code ownership across 4 product teams
  • Designed CLI tooling for scaffolding, port registration, and deployment scripts, reducing new MFE setup time from 2 days to 15 minutes
  • Implemented module-sharing strategies that reduced bundle size by 30% and supported zero-downtime rollout
  • Built Docker containerization patterns per MFE, enabling independent deployment pipelines
