You will get I'll build a REST API with Node.js and integrate it with your frontend
Project details
I build clean, well-documented REST APIs that are ready for production — not just for demos.
I've built APIs powering real SaaS products, including a multi-tenant invoicing platform and an AI-powered quote generation app. I know how to design endpoints that are fast, secure and easy to maintain.
What you get:
— RESTful API built with Node.js and Express
— Authentication with JWT or API keys
— Input validation and proper error handling
— Clean, documented code you can maintain yourself
— Full source code included
For the Advanced tier, I also handle frontend integration and deployment so your full stack is connected and live.
I use Claude Code to deliver faster without sacrificing quality. Most projects are delivered before the deadline.
If you need a solid backend, let's build it.

About Martin
Full-Stack Developer | AI Integrations & SaaS MVP Specialist
Cordoba, Argentina - 12:31 am local time
I specialize in turning complex ideas into working software — fast. My stack centers on React, Node.js, Express, MongoDB, and TypeScript, and I actively integrate AI APIs (OpenAI, Claude) to build intelligent features that solve real business problems.
What I've built:
A multi-tenant SaaS invoicing and stock management platform integrated with Argentina's national tax authority (AFIP), currently in production with real clients
A SaaS platform for quote generation with OpenAI integration, subscription payments, and a Telegram bot — live with real users
A voice-powered AI interview coach app built with OpenAI's speech API, delivering real-time conversational responses
What I can build for you:
SaaS MVPs from scratch (auth, payments, dashboards, APIs)
AI integrations: chatbots, voice interfaces, document processing, automation
Internal tools and admin dashboards
Full-stack web apps with clean architecture and fast delivery
I use Claude Code to ship faster without sacrificing quality. If you need something built right and delivered on time — let's talk.
