You will get your Next.js or Node.js authentication system fixed
Rising Talent
Project details
Authentication 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, invisible until a real user trips over them.
Real example: a live app with protected routes wide open. No JWT expiry, an OAuth callback pointing at the wrong domain after deploy, no refresh token rotation. I rebuilt the flow with proper JWT expiry, refresh rotation, Google and GitHub OAuth, Clerk sessions, and RBAC on every protected route. Unauthorized access stopped.
I work with JWT, OAuth, Clerk, NextAuth, Supabase auth, RBAC permissions, cross-device sessions, and live authentication debugging on apps already serving users. Send the details and I will tell you where it is likely breaking before anything starts.
100% Job Success and 5 stars on every reviewed contract.

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

Job Success
Gujrat, Pakistan - 8:37 am local time
100% Job Success and 5 stars on every reviewed contract. Most bugs fixed within 24 hours. Send the error first.
I work US and EU hours. Send an error at 9am EST and I am on it the same morning.
Almost every job I take starts the same way. The app runs fine on your machine, then breaks 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 server, not the code, so I read the deployed logs and build output instead of guessing.
Here is a recent one. A Node.js backend crashed only at busy times. Local tests never caught it because the database connection pool only hit its limit when real users arrived together. One config change ended it, and it has stayed up since.
✔ TRACK RECORD
▸ 100% Job Success Score
▸ 5.0 stars on every reviewed contract, no exceptions
▸ 10 live apps deployed and maintained on Vercel, AWS and Linux VPS
▸ Single bugs fixed within 24 hours, deployment failures within 48
▸ Every deployment I have taken over has shipped clean releases since
✔ WHAT I FIX
▸ Next.js deployment and Node.js deployment on any platform or your own server
▸ Vercel deployment, Railway deployment, Render, AWS deployment and VPS deployment
▸ Next.js bug fix: hydration errors, broken API routes, build errors
▸ Node.js bug fix: crashes, runtime errors, environment variable problems
▸ Authentication: JWT, OAuth, Clerk, NextAuth, sessions and RBAC
▸ Docker, CI/CD pipeline, Nginx, PM2 and Linux server management
▸ 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, AWS 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 a codebase they do not trust
✔ HOW I WORK
A lot of deployment fixes only hide the problem, so the same failure comes back on the next release. I find the real cause in the config, the dependencies or the environment, then watch several live releases before I call it done. You get a short note explaining what was actually wrong, in plain words.
✔ ONGOING WORK: WEBSITE MAINTENANCE
I currently keep 10 live apps running on Vercel, AWS and Linux VPS. Most clients start with one fix and stay for monthly website maintenance. I watch the deploys, renew SSL before it expires, keep dependencies current, and handle server management on Nginx, PM2 and Linux. When something breaks, I fix it. No new contract, no waiting.
✔ NEW DEPLOYMENTS, NOT JUST FIXES
I also set up deployments from scratch. Next.js deployment, Node.js deployment, React apps, static sites and web services, onto Vercel, Render, Railway, AWS, DigitalOcean or any Linux VPS. That includes Docker, a GitHub Actions CI/CD pipeline, domain and DNS records, SSL, and Nginx with PM2 in front. You get a deploy that runs itself on every push instead of one you have to babysit.
✔ BEYOND FIXES
As a Next.js developer and Node.js developer I also build complete apps: Server Components and SSR on the front, Express and REST APIs on the back, PostgreSQL or MongoDB for data, and auth built in from day one. Every build ships deployed and tested. Where a project needs it, I add AI features with the OpenAI API, including RAG chatbots and AI agents trained on your own data.
Send the error, the logs, or a screenshot. I will tell you what is likely wrong and what it will cost before anything starts.
