I will fix bugs and optimize your ai generated website and app
Dmitri Nekrutov
Level 1
About this gig
I review, audit and optimize AI-generated apps built with Lovable, Bolt, Base44, Replit or Claude Code and deliver a full written report so you know exactly what was wrong and what was fixed.
If your app is 70 ~ 90% done but something is broken, slow or just not working the way it should, I can help. I specialize in codebases generated by AI tools, which have very specific and recurring patterns of failure that I know how to find fast.
What I cover in every review:
- Code quality and structure audit
- Security vulnerabilities and exposed API keys
- Performance bottlenecks and slow database queries
- Broken or misconfigured API integrations
- Supabase, Firebase and PostgreSQL issues
- Stripe and payment flow bugs
- Frontend errors in React and Next.js
- Deployment configuration for Vercel and AWS
- Architecture improvements and refactoring recommendations
Every package includes a written findings report that explains what was found, why it matters and what was done to fix it. You will understand your own codebase when we are done not just get a black-box fix.
Technologies: React, Next.js, Node.js, Python, Supabase, Firebase, PostgreSQL, Tailwind CSS, Stripe, OpenAI API.

FAQ
What do I need to get started?
Just share your code (GitHub link, zip file, or live site) and briefly describe the bugs or issues you're facing. I'll take it from there.
Do I need technical knowledge to work with you?
Not at all. Just explain what's not working in plain English, and I'll handle the rest.
Will I understand what you changed?
Yes. I provide clear, simple explanations of what was fixed and how, so you're never left in the dark.
Why not just ask the AI to fix it again?
AI tools generate code well but struggle with cross-file logic, production edge cases and security. I bring human judgment, real debugging experience and accountability — and I explain every fix so you're not stuck next time.
Can you review apps built with Lovable, Cursor or Bolt?
Yes, these are my specialty. I work with AI-generated codebases every day and know exactly where they break.
What do I get after the review?
A written report listing every issue found, why it matters, and what was fixed. No black-box work — you'll understand your own codebase when we're done.
My project is 70% complete. Can you finish it?
Yes. Message me with the details and I'll recommend the right package for your situation.
Do you help with deployment?
Yes. I can review deployment config and help get your app live on Vercel, Netlify, Railway or similar platforms.
Do you sign NDAs?
Yes. Client confidentiality is fully respected.
