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, 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 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. If your auth is broken in production, or you need one built from scratch, send the details and I will tell you where it is likely breaking before anything starts. 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

Your build passes on your machine, then fails the second it goes live. A Vercel build breaks. A Railway container dies on startup. A VPS deploy falls over under real load. These problems only show up after deployment because the production environment triggers them, not your local setup. I trace the real cause from deployed logs and build output, not guesswork.
Have a broken deployment or a bug you cannot track down? Send me the error and I will tell you the likely cause before you hire me. Most single bugs are fixed within 24 hours. Most deployment failures within 48.
✔ PROVEN RESULTS:
▸ Railway deployment rescue: a Docker container dying on every push, traced to two startup environment issues and fixed, clean releases ever since
▸ Vercel deployment fix: a Next.js build passing locally but failing on every deploy, build config corrected and verified across several releases
▸ Next.js bug fix: a hydration error that only showed up in production, traced through deployed logs and fixed at the root, not patched over
▸ VPS deployment: a DigitalOcean server with Docker, Nginx, SSL, PM2, and GitHub Actions CI/CD for deploys that run on their own
▸ Auth rebuild: JWT expiry, refresh token rotation, Google and GitHub OAuth, Clerk sessions, and RBAC middleware on every protected route
▸ Render deployment fix: a Node.js backend crashing under load, environment loading and PM2 restart policy corrected
✔ WHO HIRES ME:
▸ Founders whose Next.js or Node.js app builds locally but fails on Vercel, Railway, or a VPS
▸ Teams that need a deployment fix done fast and kept stable under real traffic
▸ Clients with Next.js and Node.js bugs that only show up in production
▸ People taking over a Cursor, Lovable, Bolt, or Replit app before launch
▸ Developers who inherited an unstable production codebase
✔ WHAT I FIX:
Deployment failures tend to follow the same pattern. A Next.js build that passes locally but fails on Vercel usually hides a dependency conflict or a server-side import. Railway deploys often fail because environment variables load in the wrong order. VPS problems are commonly PM2 or process management. I start from the deployed logs and container output, trace the root cause, fix it, then verify across real production deploys.
▸ Next.js Bug Fix, Next.js Error Fix, and Next.js debugging
▸ Node.js Bug Fix, Node.js Error Fix, and runtime crashes
▸ Vercel Deployment, Railway Deployment, and VPS Deployment failures
▸ Build Error Fix and Deployment Fix across every platform
▸ Docker and Docker Compose configuration problems
▸ API routes, server errors, and environment variable issues
▸ Next.js authentication: JWT, OAuth, session, and middleware bugs
▸ DevOps: Nginx, PM2, SSL, Linux server, and GitHub Actions CI/CD
▸ Cursor, Lovable, Bolt, and Replit apps that break after the demo
✔ THE FIX THAT HOLDS:
A lot of deployment fixes only hide the symptom. I fix the root cause inside config, dependencies, or environment handling, then verify across several production releases and check the surrounding setup so the same issue does not come back on the next deploy.
✔ FULL DEVELOPMENT, NOT JUST FIXES:
As a Next.js Developer and Node.js Developer I also handle full builds:
▸ Next.js frontend, Server Components, Server Actions, and SSR
▸ Node.js and Express.js backend with REST APIs and middleware
▸ Auth using JWT, Google and GitHub OAuth, Clerk, and NextAuth
▸ Multi-tenant SaaS, RBAC, and Stripe payments
▸ TypeScript across the full stack with production build config
▸ Taking half-built or AI-generated apps to production standard
✔ TECH STACK:
▸ Next.js, React, TypeScript, JavaScript, Tailwind CSS
▸ Node.js, Express.js, REST APIs, PostgreSQL, MongoDB, Prisma, Supabase
▸ Docker, CI/CD, Linux, Nginx, PM2, DigitalOcean, Vercel, Railway, Render
Where a project needs it, I also add AI integration with the OpenAI API, AI agents, RAG, and AI automation inside production Next.js and Node.js apps, but that stays secondary to the core deployment and bug fix work.
✔ TURNAROUND:
Single bugs are usually fixed within 24 hours. Most deployment failures within 48. I also take long-term contracts as a Next.js Developer and Node.js Developer for ongoing development, deployment, and bug fixing.
Send the error or the details. Cost and timeline confirmed before anything starts.
