The problem
What you're seeing
Long sessions slow the tab to a crawl and Chrome's memory tab shows growth that never returns.
How we fix it
Our approach
We diff heap snapshots, hunt detached DOM nodes, and audit every effect, listener, and subscription. Memory growth flatlines after the fix.
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
