You will get a production-ready AI SaaS with RAG and SQL Chat using Next.js & FastAPI
Project details
The Bridge Between AI Prototypes and Profitable SaaS Assets
Most AI tools fail at scaling or monetization. I build high-performance SaaS platforms that combine Advanced RAG with Intelligent SQL Generation. This isn't just a chatbot—it’s a production-ready system designed to turn complex data into revenue.
What sets this project apart:
Dual Intelligence: Seamlessly handle unstructured data (PDF/Excel) via Weaviate and structured data via natural-language-to-SQL generation in one interface.
Modular Architecture: Built with Next.js 14 and FastAPI, the system is fully decoupled. I offer total flexibility to swap Paddle for any gateway and can rewrite the backend in Node.js or Go to fit your stack.
Revenue Ready: Includes a complete subscription engine with tiered access, daily usage limits, and webhook integration. It’s a "business-in-a-box."
Enterprise Security: Implements JWT-based auth and schema validation to ensure your AI acts as a secure co-pilot, not a data liability.
Stop buying generic templates. Get a custom, scalable AI asset designed for ROI and professional growth.

About MD Masudul Hasan
Blockchain Developer | Stablecoins, Smart Contracts, Hyperledger
Dhaka, Bangladesh - 7:10 pm local time
Recent work and how I can help you:
• Stablecoin & token development — I built a MiCA-compliant stablecoin deployed on-chain, complete with admin operations and a compliance panel
• Public & private blockchain — Hyperledger Fabric networks, smart contracts/chaincode, and full dApps
• Secure architecture — including advanced auth like passkey-based PKI in my own web apps
• Backend integration & full-stack delivery with Node.js, React/MERN, and Docker
• Modern, clean UI/UX when your project needs a polished front end
Proof I deliver: my Decentralized Escrow System was a national finalist at Blockchain Olympiad Bangladesh 2022, I hold a government-issued Blockchain Developer certification, I lead blockchain initiatives at Automa Solutions Limited, and I contribute to open-source blockchain tooling.
I focus on clear communication, clean code, and delivering exactly what you scoped. Message me your project details and I'll reply within a few hours with how I'd approach it.
