❓ Stuck building your AI-powered MVP with Lovable, Bolt, Base44, or any other tool?
You're not alone — AI tools are powerful, but when they start creating a mess, you’re left debugging AI-generated chaos. That’s where I come in.
👋 Hey, I'm Ali Haider, a Full Stack Engineer who rapidly develops MVPs and SaaS products by leveraging highly capable AI agents like Cursor, Base44, Lovable, Bolt.new, and more — to get the job done fast and securely.
🚀 Why work with me?
I’m not just a “vibe” coder — I’m a problem solver. I write real code, debug AI-generated messes, and build products that are actually ready to ship.
I can help you if you:
🧠 Got stuck using Lovable, Bolt, Base44, or Cursor — I’ll debug and get you back on track
🧩 Built your UI with an AI agent but need backend integration (e.g., Supabase, Firebase)
🧼 Have a working MVP but need clean, production-ready code that is scalable, modular, and follows best practices
🏗️ Want to build your product from scratch using solid engineering principles
💻 With 3+ years of experience building end-to-end solutions, I’ve helped startups and mid-sized companies turn ideas into real, working products — fast, clean, and with clarity.
🤖 AI Tooling & LLM Integration
I specialize in working with modern AI tools and LLM-based systems to supercharge applications with intelligent capabilities. Whether you're building an AI-powered SaaS or integrating generative AI into an existing product — I’ve got you covered.

Whether you're building from scratch or improving an existing AI product, I help you debug, optimize, and launch with confidence.
🧱 Next.js & Supabase Expertise
Beyond AI tooling, I build production-grade applications using Next.js v15 and Supabase. I’ve shipped multiple products with this stack.
With Next.js v15, I implement:
Server-Side Rendering (SSR) for performance and personalization
Incremental Static Regeneration (ISR)
App Router architecture, Server Actions, and middleware
