CRO Expert: Where Data, UX, and Tech Converge

Optimizing conversions requires the ability to analyze, design, and build.

I am a technical CRO expert. I can dig into your GA4 data to identify drop-off points, design a corrective UX variant, and personally code it in JavaScript inside your A/B testing tool — all without handing off to another team. Full autonomy means faster execution.

Why a Technical Expert Profile?

01

Implementation

Many agencies overpromise and underdeliver when it comes to clean test implementation. I guarantee bug-free execution.

02

QA & Validation

A buggy test on mobile can tank your sales. I validate every variant across all devices before going live.

03

Statistical Analysis

I don't rely on surface-level metrics. I apply Bayesian or frequentist methods to ensure result reliability.

Frequently Asked Questions

Can you test complex features? +

Yes. I can inject new functionality — such as a Sticky Add to Cart or a Shipping Bar — via JavaScript to validate user interest before committing to back-end development.

Do you analyze page load speed? +

Yes. Web performance is a major conversion factor. I audit your Core Web Vitals and recommend concrete technical optimizations.

Do you handle personalization? +

Yes. Showing different content based on whether a user arrived from Google Ads or a newsletter is a powerful conversion lever.

What is your tool stack? +

GA4 for data, Hotjar/Clarity for visual insights, AB Tasty/Kameleoon for testing, and Figma for design.
