I will add jwt authentication or crud features to your mern or nextjs app

Need user authentication or CRUD features in your MERN stack or Next.js application? I will add secure JWT-based login/signup and clean Create, Read, Update, Delete (CRUD) APIs to your project.

I'm a Meta-certified MERN developer experienced with React, Next.js, Node.js, Express, and MongoDB. I can help with:

- User registration, login, logout with JWT and password hashing (bcrypt)

- Protected routes and basic role-based access (admin vs user)

- Full CRUD APIs for any entity (posts, products, users, tasks, etc.)

- Simple frontend integration in React or Next.js (forms, protected pages, error handling)

What you'll get:

- Secure authentication flow with proper validation and error messages

- Well-structured Express routes and controllers

- MongoDB schemas and tested API endpoints

- Clean, commented code you can extend later

How it works:

1. Share your repo and describe what you need (auth only, CRUD only, or both)

2. I confirm the scope, endpoints, and fields

3. I implement, test, and send you the updated code

Already have partial auth or CRUD and need improvements? Message me first so I can confirm it fits this gig.
