About this gig
Stuck on your Lovable, Replit, or Base44 project? I can take it from here.
You've already got the idea built but now it's dragging on, and it needs the right developer to close the gap between where it is and where it needs to be.
What I can help with:
- Fixing critical bugs and errors
- Completing features that were never finished or built incorrectly
- Setting up Stripe payments and subscriptions
- Supabase or Firebase authentication, 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 AI-generated code for real users
Platforms and tools I work in:
Lovable AI · Replit · Base44 · Bolt.new · Cursor · Supabase · Firebase · Stripe · React · Next.js · TypeScript
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 I finish it.
Message me to discuss your project before placing an order.

Hi, I'm James Carl, a full-stack developer specializing in Base44 app development.
I help founders and businesses turn their ideas into fully working apps — from dashboards and CRMs to MVPs — using Base44's no-code/low-code platform. I handle everything from data modeling and custom integrations to UI polish and bug fixes.
Clear communication, fast turnaround, and clean builds that scale. If you need a Base44 app built or fixed, let's talk.
FAQ
Do I need to share my project before ordering?
Yes, please message me with details about your project first. This helps me understand the scope and confirm I can deliver exactly what you need before you place an order.
What platforms do you work with?
I work with Lovable, Replit, Base44, Bolt.new, Cursor, Supabase, Firebase, and Stripe, along with React, Next.js, and TypeScript.
My app was built with AI — can you still work on it?
Yes. I specialize in taking over AI-generated projects, cleaning up the code, fixing bugs, and completing missing functionality so it's ready for real users.
How long will my project take?
Turnaround depends on the scope of work. Quick fixes are usually completed within 1-2 days, while full project takeovers may take longer. I'll give you a clear timeline after reviewing your project.
What if I don't know exactly what's wrong with my app?
That's fine — send me access to your project and I'll review it, identify the issues, and explain what needs to be done before we proceed.
Do you offer revisions?
Yes, revisions are included depending on the package selected. We can also discuss additional revisions if needed.
Do you work on ongoing or ongoing/retainer projects?
Yes, I'm available for both one-time fixes and ongoing support if you need continued development after launch.
