I will add a real backend to your lovable, bolt, or replit app
Muhammad Zubair
About this gig
Built an app with Lovable, Bolt, Replit, or another AI coding tool? It may look complete, but many AI-generated apps lack the backend needed for real usersno proper database, insecure authentication, missing server-side logic, or incomplete APIs.
I turn AI-generated prototypes into production-ready applications by building the backend your app actually needs. Whether it's Supabase, Firebase, PostgreSQL, or MongoDB, I'll design a proper database, implement secure JWT or OAuth2 authentication, create scalable REST APIs, and connect everything to your existing frontend without breaking what already works.
My expertise includes: Node.js, Express.js, Spring Boot, Java, PostgreSQL, MongoDB, JWT authentication, OAuth2, REST APIs, and production deployments.
Before placing an order, send me your project link (or a screen recording) and tell me what your app should do. I'll review it and explain exactly what backend work is needed before you commit.

FAQ
Will this break my existing frontend?
No I build the backend to match your frontend's expectations, or update the frontend calls where needed. Everything is tested before delivery.
Can you use Supabase/Firebase specifically?
Yes, and I can also build a custom backend with Node.js/Express or Spring Boot if you need more control than a BaaS platform gives you.
What if my app has no backend at all yet
That's the most common case — I'll design and build one from scratch based on what your app needs to do.
