I architect and automate resilient security ecosystems, recently leading the DMARC hardening of 300+ domains and a 15,000-user migration from an incumbent Secure Email Gateway to Microsoft Defender for Office 365. My work focuses on replacing manual workflows with automated integrations that cut SOC investigation times by 80% and drive massive operational savings.

As a Senior Security Analyst, I stayed ahead of the curve by hunting for threats and handling incident response from start to finish. Beyond just managing alerts, I spent my time helping to tune our SIEM for better accuracy, building out our team's internal wiki, and mentoring junior analysts to help level up our SOC operations.

I handled the day-to-day work of spotting and responding to security threats across the entire enterprise. Most of my time was spent triaging potential incidents—investigating phishing attempts, malware, and rogue access points—and then deciding whether to escalate them or close them out after suggesting the right fix to mitigate the risk.

I ran security scans (DAST/SAST) for a wide range of clients, including some Fortune 500s, using tools like HP WebInspect and Fortify SCA. My job was to dig into the results to filter out the noise, manually validating vulnerabilities across everything from modern languages like Java and .NET to legacy COBOL systems, and then put together the final reports with clear recommendations on how to fix the vulnerabilities.

I kept the UNIX-based ETL system at Lexis-Nexis running smoothly, jumping in to make updates or fixes whenever QA found an issue. Most of my day was spent digging into why a job was delayed or why a production error happened, then getting those findings into a report. On the technical side, I was constantly in the weeds with Perl, XML, and IBM JCL to handle any necessary code changes, all while keeping everything tracked in WebStar.
