I’m a cybersecurity professional focused on the offensive side of security. I specialize in penetration testing, red teaming, and security assessments, helping organizations identify real-world risks and turn them into practical, prioritized improvements. My work combines hands-on technical testing with a broader perspective on secure architecture and development. I’m particularly interested in how design decisions, system integrations, and development practices shape overall security posture – and how to improve them in a way that actually works in complex enterprise environments. Beyond testing, I support teams in translating findings into actionable recommendations, bridging the gap between security, development, and business needs.
As a Senior IT Security Consultant and Cybersecurity Trainer at Securitum, I help organizations assess, understand, and improve their security across applications, APIs, cloud environments, identity platforms, endpoints, and enterprise infrastructure. My work spans both offensive and defensive security. I conduct penetration tests, red team activities, adversary simulations, and technical security assessments, while also supporting organizations with security improvements, risk reduction, architecture-oriented consulting, and practical remediation strategies. I focus on identifying realistic attack paths, understanding their business impact, and translating technical findings into clear, actionable recommendations for engineering, security, and management teams. Alongside consulting work, I deliver technical cybersecurity trainings and workshops, including for Sekurak Academy. My training activities cover both offensive and defensive security topics, with a strong focus on practical knowledge, real-world scenarios, hands-on demonstrations, and explaining how modern attacks work, how they can be detected, and how organizations can reduce the underlying risk.
