The problem
What we were solving
The client wanted a fast, mobile-first consumer surface for an Asian market where most users land on cheap Android phones over flaky mobile networks. Anything heavier than a few hundred KB of JavaScript falls off a cliff on real-world devices.
The solution
How we shipped it
We built Caicaini as a tightly-budgeted Next.js app: server-rendered content, route-level code splitting, and image pipelines tuned for low-bandwidth networks. The home view ships under 90 KB of JavaScript on the wire.
On top of that we layered the consumer features — content browsing, search, account sync — while holding the performance budget through every release with CI Lighthouse checks.
