Summary
As a Full-Stack Web Software Architect and Engineer with 15+ years of hands-on experience, I am proficient in leveraging cutting-edge technologies such as Java (versions 17 and 21), Spring Boot, Laravel, Yii2, Angular, Vue JS, JavaScript, MySQL, MariaDB, Docker, and version control using Git. I had many opportunities to manage web application servers on Linux and Windows, such as Apache, Nginx and Tomcat. I have a proven track record of contributing to fantastic projects and played a significant role in leading and collaborating with excellent teams. Most projects were on great organizations like the National Justice Council - CNJ, Brasilia Real Estate Company - Terracap, Coordination for the Improvement of Higher Education Personnel - Capes and Pan-American Health Organization - PAHO/WHO. Through my contribution, I can highlight a great variety of achievements achieved by these organizations; for example, in my current work, I developed three systems regarded as essential. The first is a Document Tracking System that enables the organization's partners to send important corporate documents with attachments. The digital mail received usually starts a new task or process in the second system, which groups all information about them. A third system is recruitment software designed to share job opportunities. Inside this software, candidates can apply for these opportunities, and the organization can follow the whole recruitment process using tools provided by the system. The software's benefits include significantly reducing paper use and accelerating internal processes beyond decreasing bureaucracy. The system also provides a single place to find most of the information. I am proud to have a bachelor's degree in business administration with analysis of Systems, an MBA in Deep Learning, and a big enthusiasm for AIs.
Qualified Java Software Architect and Engineer with an extensive background in designing and implementing complex software systems.
