About this gig
Your AI app works until it doesn't
You shipped fast using tools such as Lovable, Cursor, or Replit. It felt smooth at first but now you're hitting bugs, ballooning API bills, and unexplained behavior. Suddenly you're stuck debugging AI-generated code at 2 a.m., and the forums aren't helping
I'm a senior full-stack developer and former CTO. I've built production AI tools from scratch, scaled MVPs to real users, and integrated with everything from Gmail and Stripe to OpenAI and Supabase.
I don't just fix problems I explain what broke, why it happened, and how to prevent it next time. Think of me as a technical co-founder, not a code monkey.
Here's what I can do for you: fix bugs in Cursor or Lovable apps, clean up AI-generated messes, reduce token usage, improve prompt reliability, and build scalable features. I also handle integrations Google Calendar, Airtable, custom CRMs and deploy to Replit, Vercel, or your stack. Whatever's breaking, I'll get it working and make sure it stays that way.
Every order includes clean, code, a walkthrough (Loom or written), and up to five days of post-delivery support.
Message me to get your AI app back on track fast.

FAQ
I built this with Lovable/Replit but it's broken. Which package do I need?
If you are unsure, start with the Basic ($75 Audit). I will investigate your error logs, inspect the deployment failures, and give you a quick report explaining what is broken. If it's a quick fix, I might even solve it right there. If it's complex, you can upgrade to the higher packages later
It works in "Preview" but crashes on Vercel/Netlify. Can you fix it?
Yes, this is the #1 AI issue! AI often forgets that or uses "local-only" database settings. My Standard Package specifically fixes these build failures so your app actually runs in production
My AI code "hallucinated" a feature (like Stripe) that doesn't work.
AI often calls API endpoints that don't exist. I don't just prompt it again; I manually rewrite the logic using the official documentation (Stripe, Supabase, OpenAI) to ensure payments and data actually work
Do you support code from Cursor (VS Code) or Windsurf?
Yes! While Replit is great for starting, Cursor is for pro development. I am an expert in debugging the complex Next.js / TypeScript stacks that Cursor generates
Do I need to give you my login/password?
Never. For Replit/Lovable, send a "Collaborator Invite." For GitHub/Vercel, add my username. Your credentials stay 100% safe
My code is a mess and breaks when I add features. What do I do?
You need the Premium (Project Rescue). I will refactor the spaghetti code, clean up the file structure, and stabilize the app so you can scale it without constant bugs

Yuriy went out of his way to provide me with the best experience possible. We had a strange project to work on and I would have been loath to without him. I will most certainly be working with Yuriy in the near future.
