Message

On my Coderhouse e-commerce backend project, I developed a layered API with product CRUD operations and MongoDB.

I implemented role-based authentication with JSON Web Tokens and bcrypt, plus password recovery through Nodemailer. The project also included cart logic, stock control, and ticket generation.

I also developed TechStore, a responsive React single-page e-commerce project using Vite and Firebase Firestore to store products and purchase orders.

For PC Master Blog, I developed a full-stack web application with Django and Python, including CRUD operations, user profiles, private messaging, and a SQLite database. I’m currently studying Programming at Universidad Tecnológica Nacional (UTN) and Full Stack Web Development at Coderhouse.
