You will get a secure backend for your Lovable or Bolt.new AI app
Project details
Did you build a beautiful frontend using Lovable, Bolt.new, or Cursor, but now the backend won't connect? AI coding tools are amazing for UI, but they often leave you with a "vibe-coded" app that lacks a secure database, authentication, or scalable logic.
I specialize in bridging that gap. I turn your AI-generated MVPs into production-ready SaaS products by implementing rock-solid backend infrastructure. If you are struggling with a Bolt.new + Supabase integration or need a Lovable + Node.js backend, I can fix the bugs and build the missing pieces.
What I provide:
➤ Backend & API Setup: Connecting your React/Next.js frontend to a custom Node.js/Express.js backend.
➤ Database Architecture: Structuring PostgreSQL or MySQL schemas and fixing Supabase Row Level Security (RLS) policies so your data is actually secure.
➤ Advanced Authentication: Upgrading basic logins to Better-Auth or NextAuth, complete with Google SSO and role-based access control.
➤ Logic & Bug Fixes: Resolving API routing errors, state management issues, and third-party integrations (Stripe, AI agents).
Send me your code, and let's make your AI app fully functional!

NextJs App - Better-Auth Implementation
About Zain
Full Stack Developer | Backend Architect & System Builder
Islamabad, Pakistan - 8:01 am local time
Rather than just writing scripts, I focus on heavy-duty system design, secure API routing, and complex database management to ensure your application can handle real-world traffic without accumulating technical debt.
CORE TECHNICAL COMPETENCIES:
• End-to-End Full-Stack Development: Building highly interactive, responsive, and type-safe frontends paired with incredibly robust server environments.
• Scalable Backend Architecture: Designing secure REST APIs, handling complex backend logic, and engineering automated workflows (including WebSockets for high-performance, real-time data execution).
• Advanced Database Engineering: Structuring complex relational schemas, optimizing queries, and managing stateful connections to ensure absolute data integrity.
• System Stabilization & Deployment: Refactoring vulnerable or "vibe-coded" codebases, containerizing applications, and deploying to reliable cloud infrastructure for a secure, stable launch.
TECHNICAL STACK:
Frontend: React.js, Next.js, TypeScript, Tailwind CSS
Backend: Node.js, Express.js, Nest.js, REST API Development, WebSockets
Databases & ORMs: PostgreSQL, Supabase, Redis, Prisma, Kysely
Infrastructure & Tools: AWS, Docker, Git, Architectural Diagramming (Mermaid.js)
I prioritize rigorous testing, clear technical documentation, and strategic architectural planning before writing a single line of code.
Let’s start with a Free Code Audit to evaluate your current setup or discuss the technical roadmap for your next build. Send me a message, and let's engineer a system that performs exactly the way you need it to.
Steps for completing your project
After purchasing the project, send requirements so Zain can start the project.
Delivery time starts when Zain receives requirements from you.
Zain works on your project following the steps below.
Revisions may occur after the delivery date.
Codebase Review & Database Architecture
I will review your AI-generated frontend code to understand how it's structured. Then, I will design a secure database schema (Supabase/MongoDB) tailored exactly to your app's data needs.
Secure Authentication & Database Setup
I will set up your live database, configure Row Level Security (RLS) to keep user data private, and implement a secure login/registration system so users can access their accounts.
