Next.js Education App Developer Needed

I have a Next.js 13-based education/productivity web app built for Indian students preparing for competitive exams like NEET, UPSC, JEE, etc. The app includes features like a Pomodoro timer, productivity tracker, and AI tools. It's deployed on Vercel, but I’m facing issues with Firebase App Hosting and now want to expand functionality.
I’m looking for a skilled developer to:
Add student community chat/discussion features
Build a 1-on-1 mentorship system
Fix/transition the Firebase App Hosting deployment issue.
Tasks to Be Completed:
1. Community Feature
Build a real-time chat or discussion board for students
Users should be authenticated (Firebase Auth or Supabase)
Show user avatars, roles (like peer/mod), timestamps
Optional: Like/react to messages or threads
2. 1-on-1 Mentorship Booking
Mentors should be able to list availability slots
Students can book sessions
Option to message (text chat or external Zoom link)
Mentor profiles with bio, expertise, ratings (optional)
3. Hosting Deployment Fix
Help resolve Firebase App Hosting errors (especially Invalid Root Directory: /workspace/.next)
Or assist in fully switching to Vercel or Supabase Edge Functions for stability
