About this gig
Did an AI builder get your app to 80%, then leave broken flows, unstable code, or a deployment that fails?
I fix and complete AI-generated web apps built with Lovable, Cursor, Bolt, Replit, v0, Base44, ChatGPT, or Claude.
WHAT I CAN DO:
- Fix broken or incomplete user flows
- Fix React, Next.js and TypeScript errors
- Repair authentication and API issues
- Fix Supabase and database problems
- Resolve build and deployment failures
- Clean up unstable AI-generated code
- Add validation and error handling
- Perform targeted regression testing
TECH STACK:
Frontend: React, Next.js, TypeScript, Tailwind CSS
Backend: Node.js, NestJS, APIs, Supabase
Database: PostgreSQL, MongoDB, Prisma
WHY WORK WITH ME:
- Clean, maintainable fixes
- Clear scope before development
- Testing before delivery
- Concise handover summary
This Gig is for an existing AI-built app, not a new MVP or unlimited rebuild.
Please message me before ordering with your repository, current URL, what is broken, expected result, and error logs.

I help SaaS founders and product teams build, fix and finish Next.js and NestJS applications.
My focus is existing production codebases: bugs, unfinished features, TypeScript APIs, Stripe billing, authentication, databases, deployment and practical AI integrations.
Clients value my communication, attention to detail and work across multiple delivery phases. I define scope before coding, reduce regression risk and leave the codebase easier to maintain.
Share the issue, repository context and desired result, and I’ll recommend a fixed scope, milestones or an hourly approach.

FAQ
What is an AI-generated or vibe-coded app?
It is an app created or heavily assisted by tools such as Lovable, Cursor, Bolt, Replit, v0, Base44, ChatGPT, or Claude. This Gig covers an existing codebase that needs diagnosis, completion, cleanup, or stabilization.
Which platforms and stacks can you work with?
I primarily work with exported React, Next.js, TypeScript, Node.js, Supabase, Firebase, PostgreSQL, MongoDB, and API-based projects. I need a Git repository or source-code export; a prompt or public preview alone is not enough.
Should I contact you before ordering?
Yes. AI-built projects vary greatly in quality and scope. Send the repository, current URL, expected result, actual behavior, and error logs so I can confirm the correct package and acceptance criteria.
How is this different from your Next.js Bug Fix Gig?
The Next.js Gig is for one reproducible framework, build, runtime, or Vercel issue. This Gig is for an unfinished or unstable AI-built product flow that may require diagnosis, cleanup, and related integration fixes.
Can you finish my entire app?
Possibly, but not as an undefined package order. I will first review the codebase and create a bounded list of deliverables. Larger projects use a Custom Offer with milestones.
Can you add Stripe payments or subscriptions?
I can diagnose a small existing payment-related defect if it is part of the agreed flow. A new Checkout, subscription, webhook, or billing portal implementation belongs to my dedicated Stripe SaaS Billing Gig.
Is deployment included?
Basic includes build verification, not a full deployment. Standard or Premium may include support for one agreed environment when the hosting account, access, variables, and infrastructure are ready. Hosting and third-party fees are paid by the client.
Do you perform a full security audit?
No. I use safe coding practices and can correct security-related issues inside the agreed scope, but this Gig does not promise penetration testing, compliance certification, or a complete security audit.
What counts as a revision?
A revision corrects delivered work that does not meet the written acceptance criteria. A new feature, page, workflow, integration, business rule, or changed design is a change request and is quoted separately.
Do I need to send passwords or secret keys?
No. Never send passwords, private keys, or production secrets in chat. Use least-privilege invitations where possible and add secrets directly to the platform's protected environment-variable settings.
