shravan7572/dev-board ? reverse-engineered prompt

Build me a public developer profile app called DevBoard, where each person gets one shareable link like dev-boardapp.vercel.app/username and visitors can see their bio, skills, projects, GitHub activity, and contact info all in one place. I want a clean React front end with login and signup, profile editing, and protected dashboard pages for the owner. Users should be able to add skills with levels, add projects with images and links, and upload profile photos and thumbnails. Please include email OTP verification for signup, JWT login, password hashing, and basic rate limiting for safety. Public profiles should show GitHub contribution data, top repos, visitor reactions like fire, heart, and clap, and simple view stats with browser and device info. Use the existing client and server setup, connect it to MongoDB, Cloudinary, and email sending, and make it work smoothly end to end. If you need current docs for any service, look them up online.
