I build high-performance React and WordPress platforms for global brands, enterprise clients, and agencies.

What I'm looking for

I'm looking to build high-performance React and WordPress products where I can own delivery, solve production challenges, and improve user experience, SEO, and web performance.

I've built production web platforms for NVIDIA, Adidas Parley, and global agency clients, turning designs and complex requirements into fast, responsive WordPress and React experiences.

At IBL.ai, I led development and maintenance of NVIDIA's WordPress training platform for thousands of active users. I built custom themes and plugins, integrated 10+ APIs including Open edX endpoints, and achieved sub-two-second page loads while resolving critical production issues in under three hours on average.

For Adidas Parley, I translated Figma designs into a custom WordPress theme and integrated backend APIs for dynamic content and user data. I've also delivered headless WordPress applications with React frontends, reusable components, Gutenberg blocks, Webflow-to-WordPress builds, and WooCommerce functionality.

More recently, I've developed React and TypeScript tools such as an SEO Opportunity Analyzer, and I currently deliver luxury real-estate WordPress sites with a focus on UI/UX, Core Web Vitals, SEO, and reliable end-to-end delivery.
