I will build a secure login and authentication system
Yashrajsinh
About this gig
Need a secure way for users to sign up and log into your app? I'll build
a complete authentication system using the MERN stack (MongoDB, Express,
React, Node.js) the same technology used by production apps at scale.
WHAT'S INCLUDED:
- Signup & login with hashed passwords (bcrypt)
- JWT-based session handling
- Protected/private routes on both frontend and backend
- Clean, responsive login/signup UI
- Detailed code comments so you understand what's happening
- Full source code included
WHY WORK WITH ME:
I specialize in MERN stack development and build authentication the
right way not just "does it work" but "is it actually secure."
No plaintext passwords, no vulnerable token handling, no shortcuts.
Higher-tier packages add role-based access, password reset flows,
refresh tokens, social login (Google/GitHub), and email verification
check the packages above for full details.
Message me before ordering if your project has custom requirements
(existing backend to integrate with, specific database, multi-tenant
auth, etc.) happy to send a custom offer.

Hi, I'm Yashrajsinh, a full stack developer and SQL specialist.
I build web apps using the MERN stack (MongoDB, Express, React, Node.js) with Tailwind and Bootstrap, covering frontend, backend, database, and deployment.
I also write and optimize SQL queries: joins, subqueries, filtering, and performance tuning.
I focus on clean code, realistic timelines, and clear communication throughout every project.
Message me with your project details and I'll recommend the best package or approach for you.
FAQ
Can you integrate this into my existing React/Node app?
Yes — that's exactly what the Standard and Premium packages are built for. Send me your repo structure or a brief overview of your current setup before ordering, and I'll make sure it fits in cleanly without breaking anything.
Do you use sessions or JWT for authentication?
JWT by default, since it's stateless and scales better for most modern apps. If your project specifically needs session-based auth instead, message me first and I can accommodate it.
Can you add Google or GitHub login?
Yes, social login (OAuth) is included in the Premium package. It can also be added to Basic or Standard as a custom add-on — just ask before ordering.
What database do you use?
MongoDB by default, since it pairs naturally with the MERN stack. I can adapt to PostgreSQL or MySQL for an additional fee if your project requires it.
What if I need a revision after delivery?
Each package includes a set number of revisions (Basic: 1, Standard: 2, Premium: 3). If you need something beyond that, I'm happy to help — just reach out and we can figure out the best way forward.
