The problem
What you're seeing
Pages, layouts, parallel routes, or intercepting routes are not behaving as expected after the migration to App Router.
How we fix it
Our approach
We map the route tree, identify boundary-crossing data leaks, and refactor to match the App Router model. Streaming, suspense, and ISR work the way they should.
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
Root cause analysis with reproduction
Targeted fix with no scope creep
Verification on staging + production parity check
Runbook for future incidents
Tooling we use
Industry-standard stack, no proprietary lock-in
