Modernizing a legacy frontend through microfrontend architecture.

Reputation House had a legacy product built over several years. My work on the core team focused on bringing that legacy interface into a modern architecture without a disruptive full rewrite.

Some implementation details are omitted due to confidentiality.

I worked directly with the existing legacy codebase and implemented it into a new interface using a microfrontend architecture, as part of the core engineering team. I coordinated with other developers, participated in architecture meetings, and occasionally worked on DevOps concerns tied to the migration.

The new interface was structured as a monorepo containing a shared design system, built with Nuxt 3 and Vue 3, while legacy surfaces continued to run on Nuxt 2 and Vue 2 during the transition.

This let legacy and modern surfaces coexist behind a common shell, so the product could be modernized incrementally rather than requiring a single high-risk cutover.
