The problem
What you're seeing
Your main bundle ships 800kB+ to every visitor, including third-party SDKs they will never use.
How we fix it
Our approach
We tree-shake aggressively, code-split per route, dynamic-import every modal/SDK, and replace heavyweight libraries with lighter alternatives. Bundles drop 50%+ without losing features.
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
RUM-driven audit with line-level fix list
Implementation of every critical fix
Before/after metrics with screenshots
CI performance gate to prevent regression
Tooling we use
Industry-standard stack, no proprietary lock-in
