Beta Inc. — marketplace rebuild
Migrated a 6-year-old Rails monolith to Next.js + Postgres. 3.1s → 0.6s LCP. 2× checkout conversion.
Scroll for the work
Slow page loads (LCP > 3s on mobile), brittle deploys, and a dwindling pool of Rails engineers willing to touch the codebase.
Rewrote the customer-facing surface in Next.js with RSC, kept the admin in Rails behind a reverse proxy during the transition, and migrated commerce data to Postgres in three batches with zero downtime.
Numbers that moved.
