I find what is slowing your app down and fix it at the source: Core Web Vitals in the green, quicker loads, and before-and-after numbers to prove it.

What Web Performance Optimization involves
Speed is not cosmetic. It affects your search ranking, your conversion rate, and how your product feels to use. Slow apps quietly cost you users and money every day. Performance work is some of the highest-return engineering there is.
I audit the real field data, find what is dragging your Core Web Vitals (LCP, INP, CLS), and fix the actual causes: bundle size, render-blocking resources, slow queries, and layout shift. I cut load times by 40% on production platforms serving millions.
What you actually get
Proven speed-ups
I cut load times 40% on core micro-frontends serving 10M+ users.
Vitals in the green
LCP, INP, and CLS taken into passing range, which search and users reward.
Numbers, not vibes
Before-and-after metrics, so the improvement is provable.
Estimate your web performance optimization cost
Answer three questions and pick any extras. You get a price range and timeline instantly, and can send it straight to me for a fixed quote.
Your estimate
About 1 to 2 weeks
A ballpark to plan with, not a quote. Your answers go along with the brief, so the fixed quote comes back faster.
Or skip the quote
Build it on the Build plan at $2,490/month instead. This estimate equals about 1 month of a plan, and the plan keeps going after launch. Pause anytime.

Web Performance Optimization cost breakdown
What web performance optimization typically costs at three levels of scope. Every project still gets its own fixed quote.

|---|---|---|---|
| Starter | $1,800 to $2,250 | 1 to 2 weeks |
|
| Typical | $4,700 to $6,000 | 4 to 5 weeks |
|
| Advanced | $9,200 to $11,500 | 7 to 8 weeks |

What drives the cost
The kind of site
Content sites are mostly images and fonts. Stores and apps add scripts, data fetching, and interaction delays (INP) to fix.
- Marketing site or blogBase
- E-commerce store+$1,200
- Web app or SaaS+$1,500
The number of templates
Fixes are applied per template, so more distinct layouts mean more work.
- Up to 10 templatesBase
- 10 to 30 templates+$1,200
- 30+ templates+$2,500
The tech stack
Modern frameworks give the most control. Hosted platforms and legacy stacks limit what can change, so fixes take longer.
- Next.js or ReactBase
- WordPress or Shopify+$500
- A legacy or custom stack+$1,500
