You will get a broken AI or vibe-coded app fixed, hardened, and shipped to production
Top Rated
Project details
You built something with Lovable, Bolt, v0, Cursor, or Replit. It works in demos. It breaks with real users. The code is fragile, API keys are exposed, there's no proper error handling, and you know it won't survive production.
That's exactly where I come in.
• I take AI-generated and vibe-coded apps and turn them into clean, secure, production-ready systems. No judgment on how it was built. Just a relentless focus on making it work properly.
• What I fix: exposed API keys and security vulnerabilities, missing error handling and retry logic, broken authentication flows, unoptimised database queries, no-cost controls on AI API calls, missing environment variable setup, deployment failures, and code that works once but breaks under load.
Stack I work in: Next.js, React, TypeScript, Node.js, PostgreSQL, Supabase, Auth0, Stripe, OpenAI API, Vercel, AWS.
I've shipped production AI systems including a platform (under NDA) processing 10,000+ daily listings and a legal document analyser live on Vercel. I know exactly what separates demo code from production code.
Best fit: founders who built with AI tools and need a senior developer to make it real before launch.

Great communication. Good team player. With Abdul's expertise, sometimes we would recommend features or changes that we had not thought of. Insightful.

Build SEO-Optimized Job Board with Next.js (Bullhorn API, JSON-LD Schema, Server-Side Rendering)
This is second project Abdul finished for us and he has already started third project for us. Needless to say we are quite satisfied with his work. Every time we release a new project, we have many developers apply for the project, we do conduct interviews for each project. Yet, we've gone back to Abdul for the third time. What's different about Abdul is his communication, despite our time zone difference and work our differences, he is always responsive and sets the expectation clear. He asks thoughtful questions. As he dives deeper into the project, he provides his insights and recommendations as well.
