Summary
👤
SeniorCássio Pereira is a seasoned application security leader and educator with over a decade of hands-on experience building secure software, designing SSDLCs and integrating DevSecOps across enterprise teams. As founder and academic director of Pós AppSec and CECyber, he designs practice-first curricula that teach developers to embed security into architecture, pipelines and operations rather than treating it as an audit. His industry roles—from Application Security Engineer to R&D Principal Cyber Security Engineer at ABB and Application Security Evangelist at StoneX—showcase a track record of implementing automated security gates (SCA, SAST, DAST, IAST, IaC) and scaling security across +20 enterprises and thousands of engineers. He also combines executive experience as CTO and country director at NOVA8 with frequent teaching and advisory stints, translating complex risk and threat modeling into actionable product decisions. Based in Krakow, he pairs deep .NET-era development roots with modern cloud and edge security practice, and is an active community builder (BSidesKrakow founder and advisor) who brings rare cross-discipline empathy between developers, architects and security teams.
