I work developing RESTful using Java, JPA, Hibernate, Liquibase and Spring Boot / Node JS and NestJS / Python, Pydantic, FastAPI, Socket, SQLAlchemy and Flask and front-end using React - Ant Design, Vue.js - Vuetify and Angular - Angular Material. The databases that I ended up using in the projects were PostgreSQL, MySQL and MongoDB. In some projects were used Docker to run the services. And developing artificial intelligence using Python and making them available as a service using Flask. I got to work with the clean architecture in Java and Node JS. I use swagger to document the APIs.

In the PhD I worked on the automatic detection of resource leaks in Android mobile applications, I used machine learning (SVC, Naive Bayers, Logistic Regression, Random Forest, KNN and Deep Neural Networks) and code metrics. The research proposal was presented at the SBQS 2020 theses and dissertations Workshop. The proposal was implemented in Python. In the master's degree I worked on the development of an approach for selecting components for unit testing using artificial intelligence (genetic algorithm). Which was implemented as a plugin for the Android Studio IDE, the technologies used were: Intellij IDEA, Java, JHawk, Comment Remover, Android Debug Bridge (ADB), Spoon, TraceView and jMetal Framework. The result was published in the article “SCUTMA: Selecting Components for Unit Testing in Mobile Applications”. Data mining in the Stack Overflow question and answer repository using the NLTK (Natural Language Toolkit) LDA (Linear Discriminant Analysis) algorithm to summarize the questions related to mobile testing. Python language was used for this analysis. The results were published in the article “What are Software Engineers asking about Android Testing on Stack Overflow?”.

Developed a web system with integration with mobile application. The main technologies used are: Java, Hibernate, Spring Boot, Hibernate - React, JSX (HTML), CSS, JavaScript.

Performed software development in Java, Flutter, React Native, React, PHP, Python and Angular. Coding of web systems (front-end / back-end), mobile applications (Android) and data modeling. I also worked on error correction and integration with APIs. Some of the technologies used are: HTML, CSS, REST, jQuery, Hibernate, SVN / GIT and JavaScript. As well as MySQL and PostgreSQL databases.

I worked on developing a system for project management. The main features were: registering the projects and monitoring the team by project, having both financial and accounting expenses per project. The main technologies used are: Java, Hibernate, PostgreSQL, Oracle, PrimeFaces, JSF, HTML, CSS, GIT and Tomcat.I also helped in the development of a web system for point control. The main technologies used are: Java, Hibernate, PostgreSQL, PrimeFaces, JSF, HTML, CSS, SVN and Tomcat.

I developed a Java web system to control the frequency and punctuation of members of a Pathfinder Club. Some of the technologies I used in this project are: Java, Hibernate, PrimeFaces, JSF, HTML, CSS, GIT, Tomcat and PostgreSQL. I also developed a portugol translator for the C language. It was implemented in Java with the help of JavaCC and JFlex tools.

Performed manual and automated tests on web systems using Selenium.
