Frontend Developer / Designer — Final Website QA + Sanity CMS + Vercel Launch

I have an essentially finished website for my independent communications practice that I built using Claude. The design, copy, and architecture are established, and I'm looking for an experienced frontend developer with a strong design eye to take it through final QA and launch. This is not a redesign or new site build. I want someone to review what exists, make smart recommendations where needed, polish the implementation, and make sure everything is production-ready. Scope includes: - Review the existing codebase and clean up any issues with the AI-generated implementation - Full visual/design QA across desktop and mobile, with recommendations for any changes that would materially improve the site - Check responsiveness, typography, spacing, navigation, animations, links, CTAs, accessibility, performance, and browser compatibility - Integrate Sanity CMS into the existing Hot Takes/blog section so I can create and publish articles myself without touching code - Build the CMS-backed Hot Takes index and individual article template based on the existing design - Ensure every future Sanity article automatically gets its own permanent, shareable URL and appropriate social preview metadata/images - Ensure Hot Takes and article content are server-rendered/indexable and technically optimized for Google search and AI/answer-engine discovery - Implement basic technical SEO, including metadata, sitemap, canonical URLs, and appropriate Article, Person (Amanda Shareghi), and Organization (Ventured PR) structured data - Connect GitHub → Vercel and prepare the site for production deployment - Test the complete Sanity publishing workflow with a temporary article before launch - Perform final QA on the deployed site and help connect the live domain There are no existing blog articles to migrate. I need the publishing infrastructure set up so that future content I publish from Sanity is automatically live, indexable, and shareable. I can provide the GitHub repository, Sanity and Vercel project access, a PDF of the approved design, and all existing assets. All accounts will remain under my ownership. I'm looking for someone with experience in React/Next.js, Sanity, Vercel, responsive frontend development, technical SEO, and strong visual QA. Please send 2–3 relevant examples of your frontend work and briefly describe your experience working with Sanity CMS (or similar headless CMS platforms), along with your estimated scope/hours for this project. Please do not propose rebuilding the site on another platform unless there is a significant technical problem with the existing implementation.
