About
I’m a Creative Web Developer with 7+ years of experience building responsive, user-focused websites and applications. I specialize in React, JavaScript, WordPress, and full-stack development, delivering clean, scalable code and strong SEO for better visibility and performance. I enjoy collaborating with design and product teams to craft intuitive user experiences.
When I’m not coding, I’m exploring new technologies, refining accessibility (WCAG), and optimizing sites for performance and reliability.
