itsishant/devhub ? reverse-engineered prompt

Build me a developer community app called DevHub where people can sign up, create profiles, find other developers, send friend requests, and chat with each other. I want a clean modern interface for browsing profiles, sharing code snippets with syntax highlighting, writing and saving developer notes, and seeing an activity feed with trending posts and popular content.

Please make it feel like a real social network for developers, with things like skill endorsements, achievements, group discussions, and smart suggestions for people to connect with. Use React on the front end and a Node and TypeScript backend with MongoDB for storage. Add login with secure token based auth, password hashing, and basic input validation so it feels safe and polished.

If you need to check current docs for anything, go ahead and look them up online.
