• Docker-based MySQL setup for easy local testing

Implemented Features

• User follow / unfollow
• Timeline feed:
  • shows murmurs from followed users and self
  • pagination support
  • like / unlike with live count
• Murmur detail page
• User profile page:
  • follower / following counts
  • follow/unfollow
  • list of user murmurs
• My profile page:
  • list of own murmurs
  • delete own murmurs
• Create murmur from UI
• REST API implemented using NestJS + TypeORM

Unimplemented Features

Impressions

• Enjoyed working on a small social-feed style system.
• Focused on clarity and correctness over over-engineering.
• If extended further, authentication and authorization would be the next improvements.
