About me

I’m a graduate student with a technical degree in programming. My first experience coding was in highschool, where I learned the basics of programming and computer science. Today I keep specializing myself in backend web technologies which is what I love.

Projects

Complete Spring API

This is one of my first projects, where I put into practice everything I learned of Spring. The API allows the user to manage products and perform the basic CRUD operations, while storing all the data into a SQL DataBase.

Additionally, the application is secured with a JWT, and most of the code has unit tests to guarantee it works as espected.

Tech stack: Java, Spring, JUnit, Mockito, SQL, Hibernate

API

Magnetic stirrer

This project is a low cost magnetic stirrer, a device used to mix chemichal substances on the lab. For this project we used Arduino technologies, and I was in charge of writing the code in C++.

I also made the electronic connections on the Arduino board. We were a group of 5 people, so I gained experience working with pairs and agreeing in the terms of the development. The project was thought to be used at highschool labs, so we also had to take the requirements before we started.

Tech stack: Arduino, C++, Electronics, Team work
