I built this solo to combine CMS-driven content workflows with modern App Router patterns, server actions, and typed query contracts.

• > Implemented NextAuth GitHub login with Sanity author provisioning on first sign-in.
• > Added JWT/session callback enrichment so authenticated session state includes linked Sanity author ID.
• > Built searchable startup listing page with GROQ queries filtered by title/category/author.
• > Implemented startup submission flow using server actions, slug generation, and Sanity write client persistence.
• > Added Zod async validation that verifies submitted image URLs resolve to image content types.
• > Built startup detail pages with markdown pitch rendering and editor picks integration from Sanity playlists.
• > Implemented view tracking using post-response `after()` patch updates to increment startup view counters.
• > Added user profile pages that aggregate startups authored by a given creator.
• > Embedded Sanity Studio at `/studio/[[...tool]]` with custom structure for authors, startups, and playlists.
