Challenge

Enterprise tenants overloaded the AI scaffold that powered a React control plane, causing cold starts, memory leaks, and fractured delivery cadences.

Approach

  • Instrumented tenant-specific performance telemetry and created persona heatmaps for load testing.
  • Split the monolith into federated modules with a shared design system and versioned contracts.
  • Introduced progressive delivery with automated rollbacks, synthetic checks, and guardrail alerts.

Outcomes

  • Cut cold start latency by 68% and steadied p95 response times during peak usage.
  • Enabled parallel squad delivery with isolated pipelines and contract testing.
  • Enterprise NPS climbed 18 points within two release cycles.
