What I'm looking for

I want to build production-grade WordPress experiences—custom themes/plugins, technical SEO, and fast performance—while partnering with marketing teams on conversion-focused landing pages and using AI tools to ship efficiently without sacrificing quality.

I’m a Senior WordPress Developer with 8+ years building complete, production-grade WordPress sites from the ground up across multiple industries. I specialize in custom theme and plugin development using PHP native, ACF, CPTs, and page builders like Divi, Elementor, and Gutenberg. My deep technical SEO work has driven 40%+ organic search improvements through structured data, semantic markup, indexation control, and Core Web Vitals.

I optimize performance with Redis, Varnish, image optimization, and CSS/JS minification—often moving PageSpeed from 45 to 85+ and improving load times by 50%. I collaborate with marketing teams on GA4/GTM, conversion tracking, landing page optimization, and A/B testing, and I also accelerate development with Claude and ChatGPT while maintaining high quality.
