Profile Description

You don’t just need a developer — you need someone who can build fast, test-ready pages without breaking tracking or conversions.
.
.
I’m a CRO-focused Frontend Developer with 6 years of development experience and hands-on A/B testing and funnel development for ecommerce and marketing teams.
.
.
I previously worked with City Beauty, supporting their Marketing Operations and CRO teams. My role focused on building and maintaining high-performance test pages and funnels using pure HTML, CSS, and JavaScript.
.
.
--> What I Help Teams With
.
I specialize in CRO test development and funnel pages, including:

... Building A/B test variants (VSLs, survey pages, OS pages, landing pages)
...Updating and manipulating the DOM using JavaScript for experimentation tools (e.g. Convert . com)
...Creating lightweight, fast-loading pages optimized for paid traffic
...Implementing tracking pixels and custom events (GA4, Meta, TikTok, GTM, etc.)
...Ensuring tests run smoothly across browsers and devices.
.
--> Real-World Experience
.
At City Beauty, I:
... Built custom HTML/CSS/JS pages for live marketing funnels
... Supported revenue-focused experiments with CRO teams
... Integrated tracking, videos, surveys, and chat tools
... Converted static HTML pages into Shopify Liquid components
... Helped migrate pages into Shogun
... Worked from Zeplin/Figma designs and uploaded assets to AWS S3
... I understand speed, tracking accuracy, and experiment integrity — not just how to “make it look good.”
