Our marketing site’s jQuery front end feels slow and is hard to maintain. Please rebuild it on a modern Jamstack using Astro (island architecture) so it’s fast and easier to iterate on. All content—blog posts, case studies, and team profiles—should be sourced from our existing Contentful CMS via its GraphQL API. The new site must be fully responsive, achieve a 95+ Lighthouse score, and faithfully reflect our ‘corporate_professional’ design system implemented with Tailwind CSS.
