  • Components re-render on every keystroke

  • A written explanation of the root cause

How we approach it

The bug fixed without rewriting the application around it. We start by reproducing the problem against your real environment rather than a description of it — that diagnosis is what the fixed price is built on, and if what we find is materially bigger than it looked, you hear that before any work is agreed rather than in an invoice.
