Cybersecurity Analyst at Kryptos Technologies who automated SOC triage and reduced response time by 30%.

Message

At Kryptos Technologies, I monitored live security events in Splunk, Microsoft Sentinel, and Microsoft Defender for Endpoint, handling incidents ranging from ransomware to data loss. I also used MITRE ATT&CK to map attacker behavior and spot patterns across network, endpoint, and cloud environments.

I ran incident response from alert triage through containment and post-incident reporting. By writing Python and PowerShell scripts to automate repetitive triage tasks, I helped reduce mean response time by 30%.

Before cybersecurity, I worked at Capgemini Technology Services as an Associate Consultant focused on SAP Materials Management and Sales and Distribution. I supported SAP security and user access during migrations for 5,000+ users, and maintained practical documentation for provisioning, configuration, and access management.

At York University, I assist with cybersecurity instruction and mentor students on threat modeling and security analysis. My recent projects include security governance for the NYPD 99th Precinct case study, investigating Amazon GuardDuty findings, and a Windows Server and Active Directory lab on Azure.
