I specialize in building fast, scalable, and maintainable websites and web applications using React, Next.js, WordPress, and modern JavaScript. I blend strong UI engineering with performance optimization and efficient backend integration to deliver stable, user-focused solutions.
I develop custom websites, dashboards, booking systems, multi-role platforms, authentication, API integrations, WooCommerce features, and real-time components, all built with a performance-first and security-first approach.
With experience across frontend, backend, WordPress, hosting environments, networks, and IT systems, I provide complete end-to-end execution. From planning and architecture to deployment, optimization, and maintenance, I deliver polished user experiences supported by reliable engineering and strong IT management practices.
