You will get a full-stack web app or SaaS MVP using MERN, Next.js, FastAPI
Project details
Most developers build features. I build products — complete, deployed, and ready for real users from day one.
I specialize in full-stack web applications and SaaS MVPs using the MERN stack (MongoDB, Express, React, Node.js), Next.js, FastAPI, and PostgreSQL. Whether you have a detailed spec or just a rough idea, I can take it from architecture to production with clean, maintainable code.
What you get with every project:
✔ Responsive UI — React or Next.js with Tailwind CSS, mobile-first
✔ Secure Backend — REST APIs, JWT authentication, role-based access control
✔ Database Design — PostgreSQL or MongoDB, properly structured and optimized
✔ Admin Dashboard — full visibility and control over your platform
✔ Cloud Deployment — live on Vercel, Render, or AWS EC2
✔ Clean Code — documented, organized, and easy to hand off or extend
I have built platforms with Stripe payments, real-time features with Socket.io, multi-vendor systems, job portals, and food ordering platforms — all production-ready and handling real traffic.
If you have an idea and need an engineer who can own it end to end — let's build it.

About Bilal
Full-Stack AI Engineer | LangChain | RAG Pipelines | FastAPI | MERN
Lahore, Pakistan - 11:16 am local time
✅A young Full-Stack & AI Engineer with 2+ years of experience
Founders and product teams hire me when they need AI features that actually work in production, not prototypes. I build end-to-end: RAG pipelines, LangChain agents, FastAPI and MERN/PERN backends, deployed and running on real traffic.
✅ What I Build:
✔ AI Chatbots & Intelligent Assistants · customer support bots, document Q&A systems, and AI sales assistants built with LangChain, LangGraph, and RAG that answer from your actual data, not generic LLM knowledge.
✔ Full-Stack Web Apps & SaaS Platforms · end-to-end products with React, Next.js, Node.js, and FastAPI · from landing page to admin dashboard, built to handle real users and real traffic.
✔ RAG Pipelines & Vector Search · production-grade retrieval systems using FAISS, Pinecone, and ChromaDB that keep your AI responses accurate, grounded, and hallucination-free.
✔ Real-Time Features · live chat, notifications, and streaming responses using WebSockets and SSE that feel instant to users.
✔ Secure Backends & APIs · REST APIs, JWT auth, RBAC, and role-based systems built clean and documented so your team can maintain them.
✔ Payments & Subscriptions · Stripe, PayPal, and RazorPay integrations with billing flows that actually work at checkout.
✔ Cloud Deployments · your app live on AWS, Vercel, Render, or Netlify with Nginx, CI/CD, and setup docs so you own it completely.
✔ UI/UX & Prototyping · Figma wireframes and clickable prototypes before a single line of code is written.

Steps for completing your project
After purchasing the project, send requirements so Bilal can start the project.
Delivery time starts when Bilal receives requirements from you.
Bilal works on your project following the steps below.
Revisions may occur after the delivery date.
Project Scoping & Planning
I review your requirements, finalize the tech stack, define the database schema, and break the project into clear milestones before writing any code.
Backend & Database Build
I build the backend APIs, set up the database (PostgreSQL or MongoDB), implement authentication, RBAC, and all core business logic.
