Gig Summary
About this gig
Stuck on your Lovable, Replit, or Base44 project? I can take it from here.
You've already built the idea, but getting it finished and launched is taking forever. You need the right developer to close the gap between where it is now and where it needs to be.
What I can help with:
* Fixing critical bugs and errors
* Completing features that were never finished or were built wrong
* Stripe payments and subscription setup
* Supabase or Firebase auth, database, storage, and functions
* API integrations and third-party service connections
* Full project takeover: I review what exists and complete the rest
* Cleaning up and stabilizing generated code for real users
Platforms and tools I work with:
Lovable AI · Replit · Base44 · Bolt new · Cursor · Supabase · Firebase · Stripe · React · Next.js · TypeScript · claude code · v0
What usually happens:
Someone builds most of their app with an AI tool, hits a wall, and needs a developer to take it the rest of the way. That's the most common project I work on. You share the project, I review it, we agree on exactly what will be delivered, and then I finish it.
Please message me to discuss your project before placing an order.

FAQ
What is vibe coding, and why does my app need a review?
Vibe coding refers to using AI tools like Base44, Bolt, Cursor AI, Lovable, or Replit to quickly generate application code. AI-generated code often contains hidden bugs, security vulnerabilities, and performance issues. A thorough review ensures your app is stable, secure, and production-ready.
Can you fix bugs and optimize performance at the same time?
Absolutely! I specialize in both. I will identify and fix bugs, optimize your app’s speed, structure the code properly, and ensure it runs smoothly for real-world deployment.
What platforms and tools do you support?
I work with Vibe coding platforms like Base44, Bolt.new, Cursor AI, Replit, and Lovable. I also handle projects generated through Copilot, Codex, and GenAI, using tech stacks such as JavaScript, Node.js, React, and Next.js.
How do I know if my app is ready for production after your service?
After fixing and optimizing your app, I provide a clear final report highlighting all the improvements made, including security fixes, performance optimizations, and stability enhancements. This gives you full confidence your app is production-ready.
Should I contact you before placing an order?
Yes, I highly recommend messaging me first. Every project is different, and a quick discussion will help me better understand your needs!
