sanjana48455/Mini-MERN-project ? reverse-engineered prompt

Build me a simple full stack social media app where people can upload a photo, add a caption, and see all posts in a clean feed. I want a frontend with a create post page and a feed page, plus a backend that saves post data in MongoDB and uploads images to ImageKit. Each post should show the image, caption, and a delete button so I can remove posts from the feed. Make it responsive and simple to use, with basic routing between pages and API calls from the frontend to the backend.

Please set it up so it works locally with environment variables for the database and ImageKit keys, and make it easy to run as a small MERN project. If you need to check current docs for any library details, go ahead and look them up online.
