You will get a scalable Fullstack SaaS MVP with AI integrations in Node.js or Python
Project details
Don’t just hire a developer; hire a partner who has done it.
I am a Senior Engineer and successful Indie Maker who solo-built, launched, and scaled a paid SaaS to 1,000+ active subscribers. I apply this exact business-first mindset to your MVP, ensuring we focus on speed, scalability, and rapid time-to-market. Whether it’s traditional tech (Node.js/Next.js) or modern AI (LLMs, pgvector, RAG pipelines), I deliver production-ready products designed to generate revenue, not just code.

About Matteo
Senior Node.js & AI Backend Engineer | RAG, APIs & MVP Builder
Sarno, Italy - 7:54 pm local time
That’s exactly what I do. I’m a Senior Backend Engineer specializing in Node.js, and I help founders and companies integrate advanced AI pipelines (like RAG and autonomous agents) into their actual products.
My approach is pragmatic: I don't just blindly write code and close tickets. I care about the architecture. I'll help you pick the right tech stack, avoid over-engineering, and build a backend that won't break when your user base starts to grow.
The Backend Core: Node.js is my bread and butter (Express/NestJS). I build fast, secure, and scalable REST APIs. I also use Python (FastAPI) when we need to do some heavy lifting with AI microservices or data processing.
Databases & Caching: I know my way around both SQL and NoSQL (PostgreSQL, MySQL, MongoDB). I structure your data so queries don't take forever, and I use Redis to handle caching and queues smoothly.
AI & LLM Integration: I build systems that let AI interact securely with your private data. I have hands-on experience with RAG (Retrieval-Augmented Generation) pipelines and vector databases (like using pgvector inside PostgreSQL so we don't have to overcomplicate the stack).
The Fullstack Edge (Fast MVPs): While I am backend-first, I heavily leverage modern AI-assisted coding workflows. What does this mean for you? It means I can rapidly build clean, functional frontends (React / Next.js) and admin dashboards. If you need to launch a Proof of Concept or an MVP fast, I can handle the whole stack without you having to hire two separate developers from day one.
I believe in clean code, transparent communication, and building products that actually solve business problems.

Steps for completing your project
After purchasing the project, send requirements so Matteo can start the project.
Delivery time starts when Matteo receives requirements from you.
Matteo works on your project following the steps below.
Revisions may occur after the delivery date.
Strategic Kickoff & Tech Definition
Deep-dive kickoff call to align on business goals and refine features. We finalize the tech stack (Node.js or Python) and choose key APIs (Stripe, Twilio, OpenAI/Mistral) fitting your budget and target audience.
Architecture & Backend Setup
Configuring the PostgreSQL database schema (with pgvector for AI), setting up Redis caching, and developing secure REST APIs. Includes building full User Authentication flows (JWT or social sign-up) for a solid foundation.
