Senior🎓
Top SchoolLaércio De Sousa is an experienced IT officer and full-stack developer with 13 years supporting public-sector education and, since 2021, working on cyber incident response for the Tribunal Regional Federal da 3ª Região. He has led practical modernization projects for the Prefeitura de Mogi das Cruzes—migrating legacy Linux multiterminal labs, co-administering a Google Workspace for Education deployment, and building the municipal Education Portal using Laravel back-end and Vue.js front-end. Comfortable across JavaScript/TypeScript front-ends (Vue, Next/React, Alpine) and PHP/Laravel back-ends, he also scripts automation in Google Apps Script and contributes to open-source system tooling (notably enhancing LightDM guest-session handling with OverlayFS/BindFS and systemd-logind integration). With an academic background in physics and systems engineering, he blends analytical rigor with hands-on DevOps and security experience, often tackling cross-platform compatibility and maintainability improvements that quietly reduce operational friction.
