I was as an outsourcer for Petrobras.I had worked in a project with a React front-end and a Express JS back-end. On this project I had fully refactored the front-end in order to improve the structure and interface. I attached below an image of the design I made in Figma for this refatoration.I also worked on other two projects, mainly with Java back-end and Angular front-end.

Makeit Takeit is a game that tracks the games of an NBA team in real time. When the team scores points, the player also earns points in the game. That way the player can climb the ranking and win prizes for that.I did all the front-end using React, HTML, CSS and some other libraries.The backend was done in PHP using the Laravel framework. In addition there is also an administration panel.

Nutri is a food tracking app, where you can enter your diet to calculate your caloric intake and receive useful statistics. The app is built in React Native with a PHP backend.In summary, these were the steps of the process (several were done simultaneously): • Develop the project idea; • Model all screens and build a prototype on Figma; • Model the database and all entities relationships; • Build the database using MySQL; • Build a REST API using PHP; • Add the security layer and user control to the server using the OAuth 2.0 protocol; • Build the app itself and create several custom components; • Synchronize the application data with the server database using the best practices; • Share the app to get user’s feedback;

An important part of my activities was talking to users to understand their needs, assessing whether requests were appropriate to the business and organizing tasks with the team. Most of the developments were made on the Microsoft Dynamics AX platform using the X++ language, which required a good understanding of the underlying database. I also was responsible for building a REST API to communicate with other systems and a solution to synchronize two databases through scheduled jobs.

My main activity was to track and solve bugs on a stack based on .NET Framework and SQL Server. I also developed an XML parser in Java and worked with the team to setup a Linux server.
