Fixing Performance Degressions in Scaling React Apps

Economic & Velocity Impact

An unscalable frontend leads to a "sluggish" user experience that directly impacts conversion and retention. For the team, it means every simple change risks breaking unrelated parts of the application.

Common Symptoms

  • "Lighthouse scores dropping steadily with every new feature."
  • "The main bundle size exceeds 2MB causing slow initial loads."
  • "Prop-drilling making it impossible to refactor core components."
  • "Frequent memory leaks in complex dashboard views."

Root Cause Analysis

  • Lack of clear boundary between business logic and UI components.
  • Inefficient context usage causing global re-renders.
  • Heavy reliance on third-party libraries for simple interactions.
  • Missing code-splitting strategy for route-level optimization.

How I Solve This

I specialize in "Architecture Rehabilitation" for React. I help teams migrate to atomic design patterns, implement robust state-management boundaries, and optimize the rendering pipeline to ensure sub-second interaction times even under heavy data load.

Frequently Asked Questions

When is a rewrite better than a refactor?
Rarely. Most "unscalable" apps can be saved through strategic modularization and core-path optimization. I focus on high-impact refactors that don't stop the feature train.
Do you work with existing design systems?
Yes. I often bridge the gap between Figma designs and high-performance component libraries, ensuring accessibility and performance are baked into the base layer.
