About

I work as a SOC Analyst investigating high-volume security activity across enterprise cloud environments. On a typical shift, I triage and analyze 800–1500+ alerts spanning Azure AD, Microsoft Defender, VPN, and endpoint telemetry, identifying suspicious authentication behavior, lateral movement patterns, and policy violations. Beyond monitoring, I contribute to improving detection quality. I’ve written and optimized KQL detection queries in Microsoft Sentinel, tuned analytics rules to reduce false positives, and escalated high-severity incidents with structured analysis aligned to the MITRE ATT&CK framework. Working directly with real attack patterns changed how I see cybersecurity. I don’t just want to respond to threats I want to understand attacker behavior, simulate it, and ultimately anticipate it. To move in that direction, I’m intentionally expanding into cloud security and offensive security. I’m strengthening my knowledge in Azure identity protection, SIEM engineering, and network security fundamentals, while actively training on hands-on platforms like TryHackMe and structured SOC learning paths. I also bring a foundation in AI and machine learning, and I’m particularly interested in how behavioral analytics and intelligent detection can improve threat identification and reduce analyst fatigue. Today, I help security teams improve detection accuracy and incident response efficiency. My long-term goal is to bridge blue-team operations, cloud security architecture, and red-team simulation to build more resilient systems. If you're building a security team in a cloud-first environment, I’m open to connecting and discussing opportunities where I can contribute and continue growing.
