Architecture
Monorepos, server-first rendering and auth that works across products.
Data layer
Caching, optimistic updates and realtime. The UI never lies about state.
Pixel-perfect UI
From wireframe to production without losing a pixel on the way.
Motion
Motion with a performance budget, and a calm fallback for reduced motion.
