My expertise lies in implementing A/B testing and enhancing user experiences through data-driven decisions. I have successfully delivered over 100 experiments that significantly improved user conversion and retention rates. My focus on clean code, modular components, and fast-loading interfaces has consistently led to improved Core Web Vitals by up to 40%, resulting in better engagement and performance outcomes.

I thrive in collaborative, Agile environments and am dedicated to frontend scalability, usability, and performance optimization. At Optiphoenix, I have delivered numerous SEO-friendly websites, developed pixel-perfect mobile-responsive UIs, and improved accessibility standards.
