What I'm looking for

I seek frontend roles focusing on React and performance where I can lead teams, improve Core Web Vitals, and drive measurable traffic and conversion gains.

I am a frontend developer with 17+ years building responsive, scalable, high-performance applications across travel, e-commerce, and enterprise domains.

I specialize in ReactJS, JavaScript (ES6+), performance optimization, and SEO, consistently delivering 95+ Lighthouse scores and improving Core Web Vitals for business-critical platforms.

As a hands-on leader, I have directed and mentored frontend teams, partnered with stakeholders and backend teams, and maintained high on-time delivery and client satisfaction rates.

I focus on accessibility (WCAG 2.1), cross-browser compatibility, and measurable business outcomes—boosting organic traffic, conversions, and user engagement through thoughtful frontend engineering.
