What I'm looking for

I'm looking to build and optimize web experiments and personalization experiences where I can translate UX hypotheses into measurable improvements in user experience and conversion.

At Optiphoenix Xperts, I've developed and deployed 120+ A/B tests and personalization experiments using Optimizely, Convert, and Kameleoon.

I turn UX hypotheses and experiment requirements into responsive JavaScript, HTML, and CSS variations, validating every experience across browsers, devices, breakpoints, and key user journeys before release.

I've also built reusable web components and conversion-focused landing pages, mentored three junior developers, and contributed checkout and product-page optimization experiments that improve usability and conversion flow.
