Fixed-scope audit · Web performance
Find Out What Is Making Your Website Slow
A fixed-scope performance audit for SaaS products and e-commerce stores. I find what actually slows your site down for real users — then hand you code-level fixes ranked by impact, not a generic checklist.
Deliverables
What the performance audit gives you.
- Lighthouse and Core Web Vitals audit — lab data plus real-user field data where available
- Mobile and desktop performance analysis
- JavaScript bundle review: what ships, what is unused, what can be split or dropped
- Rendering bottlenecks: long tasks, main-thread contention, hydration cost
- Third-party script analysis — what each tag actually costs your users
- Image and font optimization review
- Network waterfall analysis: request chains, priorities, and blocking resources
- Code-level recommendations tied to specific files and components
- A prioritized action plan ranked by impact and effort
- A video walkthrough of the findings
- Optional implementation of the fixes
Who this is for
When an audit pays for itself.
- SaaS products where slow pages show up in trial conversion and churn
- E-commerce stores where every extra second of loading costs completed checkouts
- Marketing sites held back in search by poor real-user field data
- Teams that already tried the obvious fixes and need code-level answers
Measured the way Google measures it
Google evaluates real user experience through three Core Web Vitals — Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Its thresholds for a good experience: LCP within 2.5 seconds, INP of 200 milliseconds or less, and CLS of 0.1 or less. The audit measures your site against those thresholds as real users experience it, not just in a lab run.
Process
How it works.
Step 2
Fixed scope, agreed up front
A short call to confirm fit, then a written scope and quote. No open-ended billing.
Step 3
Audit, walkthrough, action plan
You get the written findings, the prioritized plan, and a video walkthrough — and can hire me to implement the fixes, or hand the plan to your team.
FAQ
Common questions.
Is this just a Lighthouse report?
No. Lighthouse is one lab signal and it is where most cheap audits stop. This audit is built on how your site behaves for real users — field data, real devices, throttled networks — and then goes into the code to explain why, with recommendations tied to specific files and components.
What do you need from me?
The URL and a short description of the problem are enough to scope it. The audit gets sharper with access to your analytics or real-user monitoring, and code-level recommendations require read access to the repository — under NDA if needed.
Can you implement the fixes too?
Yes. Implementation is an optional follow-up with its own fixed scope. It is equally fine to take the action plan and execute it in-house — the audit is written so your team can do exactly that without me.
How much does it cost?
The audit is fixed-scope and quoted after a short scoping call, because a five-page marketing site and a large SaaS application are different jobs. You will know the exact price before any work starts.

Making autonomous-driving telemetry visible, fast, and debuggable
Validation engineers can’t debug what they can’t see. I built the WebGL and D3 surfaces that turned high-frequency vehicle telemetry into something engineers could actually work with.

Security consoles can’t have bad days. At Cato Networks I modernized legacy admin infrastructure and shipped new mission-critical screens — without pausing the release train.
