A Java and Vue.js-based system used for all processes of the university like hiring, promotions, firing, requesting services, requesting purchases, and a lot more.

I participated in this project in reviewing, testing, and fixing bugs. For legal reasons I can't disclose the source code.

A Java and Vue.js-based system for project management with thousands of users. Anyone in the university can start a project, submit for approval, add team members, apply for resources, and use many other functionalities.

I developed the first version of the system alone and contributed significantly to all different versions. For legal reasons, I can't disclose the source code.

I participated in the entire program and achieved 2nd place. It is issued by the Association for Computing Machinery (ACM).

The ICPC is an extracurricular programming sport that universities around the world participate in, focusing on providing gifted students with ways to show off their skills and gain interpersonal and problem-solving abilities.

I participated in the Brazilian Mathematical Olympiad (OBM) in 2008 and earned 3rd place in the regional phase. Approximately 10,000 students participated in the state regional and 200,000 in all the country.

The OBM organizes the national mathematical olympiads, as well as several regional or state olympiads. It represents Brazil in international competitions such as the International Mathematical Olympiad (IMO) and the Iberoamerican Mathematical Olympiad.

The OBM reaches a wide range of students of private and public schools throughout the country.

Achieved 2nd place in the Topcom state programming contest.

This contest provides computer students with the opportunity to demonstrate, share, and improve their problem-solving skills using the computer.

The tournament consists of solving and implementing a list of issues within a specific time frame. The elaboration and correction of the problems have the participation of professors from the Department of Informatics at UFES.

A single sign-on system that enables users to log in only once and use all the systems in the university.

A system where candidates can apply to try to join the university. The system implements a complex ranking process where the candidates are analyzed by up to five different teams to be approved and enroll in the university.

A system for registering courses, disciplines, classes, student grades, and everything related.

I worked in this system reviewing the code, fixing bugs, refactoring the code, and developed the process of identifying students with poor performance to assign them a team to help.
