About this gig
Your AI-built app looked finished until real users showed up.
White screens. 500 errors. Broken auth. A Supabase query that works in preview and dies in production. Tools like Lovable, Bolt, Cursor, and Replit ship great demos but the code underneath is often messy, insecure, and not ready for real traffic.
Try the interactive demo: https://demo-before-and-after-fix-seven.vercel.app
I'm a full-stack MERN developer, comfortable across both NoSQL and SQL (Postgres, MySQL with Prisma and Drizzle). I don't just re-prompt the AI and hope I read the actual code, find the real cause, and fix it. I also build and run my own live SaaS, Forge, so I know what an app needs to survive real users.
I fix: white screens, crashes, failed deploys, 500/CORS errors, broken API calls, auth & login (JWT/sessions), database issues, exposed keys, and half-finished features.
What's different: every order includes a clear report what was broken, why, and exactly what I changed. No black box.
One bug or a full rescue I'll get it working.
Message me before ordering and I'll review your app for free and suggest the right package.

I’m a full-stack developer primarily working with the MERN stack to build fast, scalable SaaS applications.
I focus on turning ideas into real, usable products, from MVPs to full production-ready web apps. My approach is clean architecture, practical engineering, and building features that actually ship and perform.
With a strong interest in AI-powered development workflows and modern product engineering, I help clients build software ready for rapid iteration and today’s fast-moving development landscape.
If you need someone to turn your idea into a working product, I can help.

FAQ
What counts as a "vibe coded" app?
Any app built with AI tools like Lovable, Bolt, Cursor, Replit, v0, or Claude Code, where the demo works but the code has bugs, security gaps, or unfinished features.
Which tech stack do you support?
I specialize in MERN stack with support of both SQL & NoSQL database.
Do I have to share my passwords?
No. For most platforms you can invite me as a collaborator or share a repo link with limited access. We'll choose the most secure option before starting.
My app is live and crashing, can you help urgently?
Yes. Message me first so I can confirm availability and fast-track it. Extra-fast delivery is available as an add-on.
Will fixing one thing break something else?
No. I check how each change interacts with your existing code before deploying, and every fix is documented in your report, so nothing is a mystery.
Do you only fix bugs, or can you finish my app?
Both. I fix bugs, complete unfinished features, wire up backend, auth, and payments, and can deploy your app live. See the Standard and Premium packages.
What do you need from me to start?
A short description of the problem, access to your code or platform, and your backend details (Supabase/Firebase) if you have them.
