What I'm looking for

I'm looking for a security operations role where I can investigate and escalate incidents, improve detections and playbooks, hunt threats, and grow further in Microsoft security technologies, CrowdStrike, and SIEM operations.

I've monitored, analysed, and triaged 50+ security alerts per shift as a SOC L1 Security Analyst at Duskbeacon, escalating confirmed incidents with root-cause analysis and technical documentation.

Through Clarusway's Cybersecurity Analyst Programme, I built hands-on experience across Microsoft Entra ID, Azure IAM, CrowdStrike Falcon, Splunk Enterprise Security, IBM QRadar, vulnerability management, and MITRE ATT&CK-based threat detection. I also bring a frontend development background from BD Electronics Ltd. and freeCodeCamp, helping me understand application-layer attack surfaces and secure web development.

I built Sentinel Log Core, an open-source C++17 security toolkit for detection rules, IOC extraction, threat-intelligence matching, event correlation, and MITRE ATT&CK mapping. I'm also an active YesWeHack bug bounty hunter and have submitted responsible disclosures to Mitsubishi Motors Deutschland and GLS.
