About Gabriel

Fullstack Developer specialized in Node.js / NestJS / React / PostgreSQL, I assist companies in the design and development of their web applications.

My approach emphasizes code quality, scalability, and a clear, sustainable architecture.

I design robust APIs in Node.js (NestJS), intended to power your web or mobile applications, and ensure seamless front-end integration with React.

On the data side, I primarily use PostgreSQL, which I structure to guarantee reliability, performance, and scalability.

All of this can be deployed on your cloud environments (AWS, Render, Koyeb, etc.), with simple and documented setup.

    💌 Drop — Send a postcard via a WhatsApp message

    Drop is a simple and innovative service that allows you to send real printed postcards from a simple WhatsApp conversation.
    The user sends a photo, a message, and an address; Drop takes care of the rest: printing, postage, and shipping, worldwide.

    The project is based on a modern stack (NestJS, React, PostgreSQL) and a scalable architecture, integrating the WhatsApp Business API, Stripe for payments, and an automated partner printer.
    Drop stands out for its fluid user experience, without requiring any app or account creation, and for its viral growth loops through an integrated referral system.

    Objective: make sending a postcard as easy as sending a message. 💌
