What You Get

The Rapid Response Model

Sometimes you do not need a full architectural overhaul. You need an expert to look at a specific problem and provide an immediate solution.

This is a focused engagement designed to unblock your engineering team. We skip the reports and meetings to go straight into the code.

1. Live Debugging

We share screens and dive directly into your codebase or performance profiler. I identify the exact cause of your layout shift, interaction delay, or load time regression.

2. Immediate Implementation

I do not just point out the error. I guide your developers on how to fix it. In many cases, we write the patch together during the call.

3. Expert Validation

If you are planning a migration or a new feature, I validate your approach before you commit resources. This prevents expensive performance mistakes before they happen..

Your frequently asked questions answered

I understand that hiring a Core Web Vitals consultant might not be your everyday playbook. These are the questions that I answer the most. If your question is not in here do not hesitate to contact me!

Immediate Impact & Speed

How quickly can you fix our Core Web Vitals issue?

We start immediately. We jump straight into your codebase or performance profiler. For most isolated issues,like a layout shift on checkout or a specific INP failure, we identify the root cause within the first hour and often implement the patch live during the session.

Is this just an audit, or do you actually fix the code?

This is a hands-on engagement. I am here to solve your problems directly. I guide your developers through the specific code changes required, or I write the code examples myself. You leave the session with a verified solution.

Can you guarantee a pass for our upcoming release?

I guarantee I will find the fastest path to a passing score. If you are blocked from launching due to poor performance metrics, I prioritize the specific "quick wins" and architectural adjustments needed to clear the threshold immediately. We focus on passing the audit so you can ship.

Process & Technical Access

Do we need to sign a long-term contract?

This is a "pay-as-you-need" service. You book a slot, we fix the problem and we are done. It is the fastest way to access enterprise-level expertise without onboarding delays or commitments.

Do I need to grant you full access to our infrastructure?

We typically work via screen sharing or pair programming sessions. Your developer drives, and I navigate. This bypasses complex security compliance and access management, allowing us to start debugging your production or staging environment instantly.

What stacks do you support for on-call debugging?

I support any stack that runs in a browser. The browser's rendering engine functions the same way regardless of whether you use React, Angular, Magento, or vanilla JS. I debug the runtime performance,Javascript execution, layout thrashing, and resource loading. If it renders in Chrome, I can optimize it.

Billing & Flexibility

I am not sure if I need 2, 4, or 8 hours.

Start small. I am highly efficient. Most specific questions are resolved in the 2 hour block. If we uncover a deeper architectural issue, we can simply extend the session or book a follow-up. You only pay for the time we use to solve your problem.

Can we split a 4 or 8-hour block into multiple sessions?

Yes. Flexibility is key. We can use the first session to diagnose and implement a fix, and a second session days later to review the impact and refine. You control how we utilize the time to best fit your sprint cycle.

What if we don't fix the issue in the booked time?

I assess the feasibility of the fix immediately at the start of our session. If the issue exceeds the booked timeframe, I inform you before we proceed. Once I commit to a resolution within the agreed time, I own that deliverable. If the work takes longer than my estimate, I complete the fix at my own expense. I take full responsibility for the estimation.
