You will get your Next.js or Node.js auth and OAuth system fixed
Rising Talent
Project details
Auth problems hit users the moment you go live: random logouts, OAuth redirects landing nowhere, protected pages open to anyone with the link, sessions resetting on refresh. These almost always trace to one or two specific mistakes in the token or session logic.
Real example: a live app with protected routes wide open. No token expiry, an OAuth callback pointing at the wrong domain after deploy, no refresh token rotation. I rebuilt the flow with proper token expiry, refresh rotation, Google and GitHub OAuth, Clerk sessions, and RBAC middleware on every protected route. Unauthorized access dropped to zero.
I work with JWT, OAuth, Clerk, NextAuth, Supabase auth, RBAC permissions, cross-device sessions, and live auth debugging on apps already serving users. Most single issues are fixed within 24 hours.

Versel setup
I would like to sincerely thank you for the outstanding work and professional administration of the website. Overall, the entire collaboration turned out to be extremely positive, reliable, and highly professional from start to finish.
At the very beginning, communication was a little bit difficult and somewhat unstructured at times, which can naturally happen in more technical and complex projects. However, what truly stood out was the continuous improvement throughout the entire process. Communication became better and better over time, much clearer, more organized, and significantly more efficient.
As the project progressed, there were no misunderstandings anymore regarding the tasks or requirements. Everything was discussed properly, questions were clarified quickly, and the implementation process became very smooth and professional. It was obvious that great attention was given not only to the technical aspects, but also to understanding the actual goals and expectations behind the project.
One thing I especially appreciated was the willingness to improve communication and adapt during the collaboration. In the beginning, a few details required additional clarification, but afterward everything worked perfectly. The tasks were understood correctly, handled professionally, and implemented exactly as requested.
The final result was absolutely excellent. The website administration, technical adjustments, and overall execution were completed perfectly and fully met my expectations. Even smaller details were handled carefully, which clearly demonstrates professionalism, dedication, and technical expertise.
In the end, everything turned out very well, and I am genuinely satisfied with the entire experience. The collaboration improved continuously, communication became excellent, and the final implementation was simply outstanding.
For that reason, I am very happy to give a full 5-star rating and can highly recommend this service without hesitation. Thank you very much for the professional support, the patience throughout the process, and the excellent final results

Fix Railway Deployment for Next.js with Clerk Authentication
Hamza, was a pleasure to deal with, responsive, great communicator and excellent work quality.

Job Success
Gujrat, Pakistan - 3:52 am local time
I am a Next.js developer and Node.js developer specialized in bug fix, debugging, and deployment work across the full stack: React, JavaScript, and TypeScript on the frontend, Node.js and Express on the backend.
The pattern behind almost every job I take is the same. The app runs fine on your machine, then fails the moment it goes live. A Vercel build that passes locally and dies on deploy. A Railway container that crashes seconds after startup. A VPS that falls over under real traffic. These bugs live in the production environment, so I read deployed logs and build output instead of guessing from the source code.
Recent example: a Node.js backend that crashed only at peak traffic. Local tests never caught it because the database connection pool only hit its limit under real concurrent users. One config change ended it.
✔ WHAT I FIX
▸ Vercel deployment, Railway deployment, Render, and VPS failures
▸ Next.js bug fix: hydration errors, broken API routes, build errors
▸ Node.js crashes, runtime errors, and environment variable problems
▸ Authentication: JWT, OAuth, Clerk, NextAuth, sessions, and RBAC
▸ Docker, CI/CD, Nginx, PM2, and Linux server issues
▸ Apps built with Cursor, Lovable, Bolt, or Replit that broke after the demo
✔ WHO HIRES ME
▸ Founders whose app builds locally but fails on Vercel, Railway, or a VPS
▸ Teams that need production stable again fast
▸ People who built an app with AI tools and need it finished properly
▸ Developers who inherited an unstable codebase
✔ HOW I WORK
A lot of deployment fixes only hide the symptom, so the same failure comes back on the next release. I fix the root cause in the config, the dependencies, or the environment handling, then verify across several production deploys before calling it done. You get a short note explaining what was actually wrong, in plain words.
✔ BEYOND FIXES
I also build complete apps as a Next.js and Node.js developer: frontends with Server Components and SSR, Express backends with REST APIs, PostgreSQL or MongoDB, TypeScript across the stack, and auth built in from day one. Every build ships deployed and tested on Vercel, Railway, or a VPS. Where a project needs it, I add AI features with the OpenAI API, including RAG chatbots and AI agents grounded in your own data.
✔ TURNAROUND
Single bugs: usually within 24 hours. Deployment failures: usually within 48. I also take long term contracts for ongoing development, deployment, and maintenance.
Send the error, the logs, or a screenshot. I will tell you what is likely wrong and what it will cost before anything starts.
