Taras Vovk
Lead Instructor
Spent eight years as a penetration tester before moving into security education. Runs the live webinar sessions and designs the hands-on lab environments used throughout the program.
Web Application Security
Where code meets consequence
A structured program from Skelvorad examining how web applications fail under attack — and what engineers do differently when they understand the mechanics behind each vulnerability class.
What the program actually covers
Most security courses describe vulnerabilities in abstract terms. This program works differently — each module starts with a real application scenario, identifies where the code goes wrong, and traces the consequences through a realistic attack chain. OWASP Top 10 serves as a structural backbone, but the material goes deeper into authentication flaws, insecure direct object references, and API-specific risks that generic checklists often miss.
Sessions run as live webinars with recorded access afterward. Instructors demonstrate exploitation in sandboxed environments, then walk through the remediation decisions — including the tradeoffs that make security choices genuinely difficult in production systems.

Dmytro Kachur
API Security
Focuses specifically on REST and GraphQL attack surfaces. Leads the API security module and provides written feedback on participant assessments.
Olena Bryts
Secure Development
Works with development teams on integrating security into their existing workflows. Covers threat modeling and secure code review practices in the program's later modules.
Bohdan Sych
Auth Systems
Specializes in authentication and session management vulnerabilities. Leads the module covering broken auth patterns and the implementation details that make them exploitable.
