About this gig
You vibe-coded something. Now it's broken, leaking data, or you've hit a wall no AI can explain its way out of.
I've seen this exact moment hundreds of times. The Lovable app that looks perfect but has zero Row-Level Security. The Cursor project that worked locally and dies on Vercel. The Bolt build where the AI kept looping and now nothing makes sense. The Claude Code session that rewrote the wrong files.
That's not a prompt problem. That's an architecture problem. And that's what I fix.
What I do:
- Debug and fix Lovable, Bolt, Replit, v0, Cursor, and Claude Code projects
- Repair broken Supabase auth, RLS policies, and database schema
- Fix failed Vercel, Railway, and AWS deployments
- Audit AI-generated code for security vulnerabilities
- Redesign broken architecture before your tech debt becomes unfixable
- Add real auth, payments, and data integrity your AI skipped
Why me: I am a full-stack engineer who works fluently in the same tools you used to build. I don't just patch surface errors. I find the root cause fast.
Most clients go live within 24 to 48 hours.
If your vibe-coded app is stuck, broken, or not safe for real users, this is the gig.

I’m a Senior Backend & AI Engineer specializing in FastAPI, AWS, and production-grade LLM systems.
I build scalable APIs, AI agents, RAG pipelines, and automation tools using Python, LangChain, and vector databases—with a strong focus on reliability, performance, and security.
Engineering-first approach:
Clean architecture, cloud-native deployment, clear documentation, and maintainable code. If you’re building AI-powered infrastructure, I’ll help you ship it the right way—from MVP to production.

FAQ
My app was built with Lovable, Bolt, or Cursor. Can you work with it?
Yes, these are exactly the tools I specialize in. I know how each one generates code and where each one fails. Send me your project and I will tell you what is wrong within hours.
Why is my vibe-coded app broken if the AI said it was done?
AI tools get you 80% there fast. The remaining 20% is where real apps live. Security policies, proper auth, database integrity, deployment config. These are things AI skips or gets wrong consistently. That is what I fix.
My app works locally but breaks after deployment. Can you fix that?
Yes, this is one of the most common issues I see. Environment variables, Supabase RLS, CORS errors, and DNS misconfigs are almost always the cause. Most clients are live within 24 hours of ordering.
Is my app actually a security risk right now?
Possibly yes. Around 80% of vibe-coded apps ship with critical security gaps including exposed API keys, missing Row-Level Security, and broken authentication. The Basic audit package will tell you exactly where you stand.
