• Configure and improve CI / CD workflows for frontend delivery, including Vercel pipelines and global environment tuning.
• Use modern rendering patterns (SSG, SSR, ISR) to achieve fast, reliable UX and strong Google PageSpeed outcomes.
• Architect personalization and real-time content / data experiences with Sitecore CDP / Personalize and Sitecore Search.
