🐛 Why the Dev Server Won't Start

There's a pre-existing route conflict in the codebase (not related to our implementation):

app/api/freelancers/[id]/     ← Existing
app/api/freelancers/[userId]/ ← Existing (causes conflict)

Next.js requires the same slug name for dynamic routes in the same directory.

Fix Options:

  1. Rename one of the routes
  2. Merge the routes
  3. Move to different parent paths

See ROUTE_CONFLICT_FIX.md for detailed solutions.
