Ernest Doe

I’m a cybersecurity analyst with hands-on experience in security operations, vulnerability assessment, and digital forensics. My work centers on incident investigation, SIEM-driven triage, and security testing that translates findings into clear technical reports.

In my recent role as an Assistant Technology Officer, I identified and analyzed security vulnerabilities that supported prerelease remediation of 50+ medical devices, helping drive an 80% reduction in post-release defects. I triaged 250+ security alerts in Splunk, targeting high-risk threats while reducing false positives by 18% to speed up response to critical events.

I also develop and improve detection capability—writing and optimizing 20+ Splunk detection rules to increase threat visibility across endpoints and improve alert accuracy. Alongside this, I conducted research on healthcare data protection and secure medical device integration, aligning assessments with PIPL, GDPR, and HIPAA requirements.

Before that, I worked as a Web/App Tester (freelance, remote), performing functional and security testing across 100+ web and mobile applications. I carry that same disciplined approach into my projects, like my digital forensics investigation lab using Autopsy and FTK and a network scanning/vulnerability assessment project using Nmap.
