Bartosz Pietrucha is a Polish Angular educator and the founder of Angular Architects, focused on the architectural patterns that scale Angular applications past the toy-project size. He is a frequent NgConf speaker and publishes paid courses on advanced Angular and web-security topics.
His CourseFlix listing carries Web Security Dev Academy — 12-Week Program — a comprehensive walkthrough of the OWASP attack categories, the defences against them at the application layer, and the security-engineering patterns that show up in production codebases across Angular, Node.js, and TypeScript stacks.
Material is paid and aimed at developers ready to take application security as a deliberate engineering discipline. For broader content, see CourseFlix's Web Security & Pentesting category page.
