At Qintess / Polícia Militar da Bahia, I develop and maintain institutional systems, including Java 21 and Spring Boot 3 microservices for Portal PM 360. My work includes OAuth2 APIs and an SSO authentication BFF with Keycloak and LDAP.

I also develop and maintain institutional web systems with PHP 8.4, Laravel 12, Vue 3, PostgreSQL, and Docker. I use modular architecture and Scrum in this work.

Before Qintess, I developed and maintained public and internal web systems at Transalvador using PHP, Laravel, and Yii2. I currently also teach professional education at SENAI, supporting students in Systems Analysis and Development.
