What We Do

Performance Diagnostics

  • Lighthouse & Web Vitals analysis
  • Rendering cost observation
  • Bundle weight & payload inspection
  • Hydration cost analysis
  • Network waterfall & third-party impact
  • Cache header & delivery strategy review

Architectural Signals (Behavior-Based)

  • Server vs Client rendering detection
  • CSR vs SSR pattern analysis
  • Route-level chunking observation
  • Static vs dynamic delivery signals
  • Structural scalability risk indicators
  • Rendering boundary pressure signals

Reliability Surface Analysis

  • Double submission risks
  • Race condition symptoms
  • Loading & retry inconsistencies
  • Hydration mismatch detection
  • State desynchronization signals
  • Error handling & recovery gaps

How We Work

  1. Production behavior mapping
  2. Runtime & delivery diagnostics
  3. Structured technical report
  4. Prioritized improvement roadmap

What This Is

This audit analyzes observable production behavior — no repository or infrastructure access is required.

Deep internal code reviews can be offered separately.

Why It Matters

Frontend systems degrade silently.



Signal identifies structural weaknesses from production behavior — before they become systemic failures.
