What I'm looking for

I’m looking to build and tune detection logic and automated incident response workflows that reduce triage and MTTR. I want to partner with engineering and security teams to improve coverage, lower false positives, and ship reliable playbooks for cloud-native systems.

I’m a Senior Detection and Response Engineer with 10 years of experience building secure, reliable systems across healthcare and SaaS environments. I focus on incident response, anomaly investigation, detection logic, and automation—turning noisy signals into actionable detections, playbooks, and repeatable response processes.

At Spring Health and Optum, I built tooling and workflows that improved alert triage, reduced investigation time, and strengthened response across distributed services and data platforms. I partner well with engineering and security teams, ship quickly under pressure, tune thresholds to reduce false positives, and strengthen monitoring coverage while driving measurable improvements in MTTR.
