Senior Front-End Developer building modern, high-performing web experiences.

I design and build polished, user-focused digital experiences with deep experience across CMS platforms, e-commerce solutions, and production-ready front-end development.

About

Built on real-world delivery experience.

I’m a Senior Front-End Developer with over 15 years of experience building websites, CMS implementations, and e-commerce solutions across multiple industries. My background includes Sitefinity, WordPress, NopCommerce, Sitecore, Vue, and production-focused front-end development in collaborative agency and client environments.

Beyond implementation, I work closely with designers, strategists, developers, and stakeholders to translate business goals into clean, maintainable, user-focused digital experiences. I’ve led client calls, presented work, supported technical planning, and helped guide projects toward successful outcomes.

This site reflects where my experience is going next: combining a strong production background with modern React and Next.js development.
