Summary
👤
Senior🎓
Top SchoolSidney Ribeiro is an Assistant Director and application security specialist with 10 years of experience securing web applications, APIs and microservices across enterprise and public sectors in Brazil. He blends deep hands-on software development (PHP/Laravel, Node.js, full-stack) with advanced AppSec practices including SAST, DAST, SCA, threat modeling and red/blue team engagements. At Moody’s and HostGator he led vulnerability triage, automation and secure code review workflows, while earlier roles in government and consulting added regulatory and incident-response experience (including LGPD/PCI). Sidney’s academic background in computer science, including CUDA-based research on big data joins, underscores a pragmatic curiosity about systems “under the hood” and how to break them constructively. He’s equally comfortable shipping features and running pentests, and often focuses on turning automated tool findings into actionable remediation and developer-friendly security guidance.
