🚀 Featured Project

NetworkPolicy Intelligence System (NPI)

A six-layer security observability platform for OpenShift/Kubernetes, built as my End-of-Study Engineering Project (PFE) at NextStep IT, in partnership with TEK-UP University.

Combines OVN-Kubernetes flow analysis, statistical + ML anomaly detection (Isolation Forest), an 8-rule NetworkPolicy compliance auditor, and a fully on-cluster LLM assistant (Ollama/llama3.2:3b, zero data egress) into a live dashboard with real-time compliance scoring.

🧠 About Me

I'm a network and cloud security engineer with hands-on experience in networking, cloud/container security, and security analysis. My work bridges theory and real-world implementation — from Kubernetes-native security platforms to ISO 27001–aligned monitoring architectures and secure network infrastructure.

I actively work with Kubernetes/OpenShift, Linux environments, Python, and network simulation tools to design and demonstrate security concepts such as anomaly detection, NetworkPolicy compliance, access control, and secure architecture design.
