Detection and Response Lead at Tenchi Security, designed Zanshin’s detection pipeline and grew it to 1,600+ rules.

At Tenchi Security, I lead the research team behind Zanshin and designed its detection pipeline for data collection, analysis, enrichment, and storage. I grew its detection-as-code base to more than 1,600 rules, helping customers fix 90% of critical alerts within their first two weeks on the platform.

I research how attackers abuse cloud environments and turn their tactics into actionable detections, presenting this work at DEF CON, fwd:cloudsec, and SecTor. Before Tenchi, I led network security at the Rio de Janeiro State Court, where I started threat hunting, and co-founded BlueOps, a Blue Team and threat detection company.
