I will fix and finish your lovable, bolt, v0 or cursor app
Zsombor Horvath
About this gig
You vibe-coded an app with Lovable, Bolt, v0 or Cursor and got 80% of the way before it broke. Auth won't work, the database won't connect, it won't deploy, or the AI just keeps making it worse. I take it the rest of the way.
I'm a software engineer who actually reads the code the AI generated so I fix the real problem instead of re-prompting and praying.
What I do:
- Fix bugs, broken auth and deploy failures
- Connect your database, payments (Stripe) and APIs
- Finish the half-built features and clean up the mess
- Ship it live to production (Vercel, Netlify, your own domain)
Works with Lovable, Bolt.new, v0, Cursor, Replit, Supabase, Next.js and React.
You get a working, production-ready app plus a plain-English explanation of what was wrong and how I fixed it, so you're not stuck again.
Message me your preview link or repo before ordering and I'll tell you exactly what it needs. Let's get your app shipped.

Hi, I'm an AI engineer at Amazon who ships production systems, not demos. Besides creating traditional software systems (webapps, mobile apps), I also build custom AI agents, RAG chatbots grounded in your own data, and AI automations that hold up in the real world (LangChain/LangGraph, Claude, vector DBs, Python & TypeScript). Track record: a RAG platform with citations + hallucination control, an AI code-review agent that cut review time 80%, and web apps serving 6,000+ users. Message me and let's scope your project.

FAQ
Can you fix an app even if the AI wrote messy code I don't understand?
Yes — that's exactly what I do. As a software engineer I read the generated code, find what's actually wrong, and fix it properly. You don't need to understand any of it. Just send me the app and tell me what's not working.
What do you need from me to get started?
Your app's preview/live link or repo, access to the platform it's on (Lovable, Bolt, v0, Supabase, etc.), and a short list of what's broken or unfinished. I'll send a quick checklist after you message me so we don't lose time.
Which tools and platforms do you work with?
Lovable, Bolt.new, v0, Cursor and Replit, plus the stack underneath: Supabase, Postgres, Next.js, React, Stripe and most APIs. I deploy to Vercel, Netlify or your own domain. If your app runs on it, I can almost certainly work with it.
Can you finish features that aren't built yet, not just fix bugs?
Absolutely — 'finishing' is half the job: connecting the database, adding auth and payments, completing half-built screens, and wiring up features the AI couldn't. Tell me what the finished app should do and I'll build the gap.
What if my app is too broken to fix?
I review it first and tell you honestly. Most apps are very fixable. If yours is genuinely beyond saving, I'll say so and quote a clean rebuild instead of charging to patch something that won't hold. You'll know your options first.
Will I own the code and be able to keep editing it?
100% yours. I leave the code clean and explained, so you can keep building in your AI tool, hand it to a developer, or have me continue. No lock-in, no black box, and Premium includes full documentation.
Do you deploy it live, or just fix it locally?
I get it actually live — deployed to production on Vercel, Netlify or your domain, working for real users, not just running on my machine. Standard and Premium include deployment, so your app is shipped, not just fixed.
