• Support migration of approximately 260 marketing pages and 600 templated store detail pages
• Write or support transformation scripts to convert AEM content structures into Sanity-compatible documents
• Assist with bulk content imports and validate data integrity post-migration
• Collaborate with delivery, UX, and engineering teams to maintain strict scope control and timelines

• 3–5+ years of frontend development experience in enterprise ecommerce environments
• Strong experience working with headless CMS platforms, preferably Sanity
