I helped architect the Contentful model for the entire site, including hospitals, services, events, and provider directories. On the frontend, I built reusable React components with accessibility baked in, and integrated them into a Storybook library used by the entire team. I implemented draft content previews using Next.js app/preview routes and Contentful’s Preview API, which enabled stakeholders to review changes before publishing. I also set up webhook-based CI/CD deployments through Vercel, so that new content could be published or previewed instantly. One of my core contrib
