FAQ
Questions, answered.
React or Vue?
Team + ecosystem decide; we ship both, RSC-first where it pays.
Is SSR always needed?
No - we measure first; dashboards often ship as client-rendered islands.
Can you migrate a legacy JS app?
Yes - strangler pattern, component by component, zero big-bang.
Do we need a PWA?
Only if offline/push earn their keep; we size the need first.
How do you guarantee CWV?
Budgets in CI + LHCI gates; targets written into the contract.
Do you handle design too?
Yes - design system and UX audits are in-house.
