The problem
What you're seeing
Lists with 500+ rows lag, charts re-paint on resize, and animations drop frames on mid-range hardware.
How we fix it
Our approach
We virtualise lists, memoise heavy charts, throttle resize handlers, and move expensive work into web workers. Rendering hits 60fps even under load.
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
Audit of the failing component tree
Refactor with memoisation + stable deps
Regression tests for the fixed paths
Hand-off doc explaining what changed and why
Tooling we use
Industry-standard stack, no proprietary lock-in
