Senior Security Engineer · Self-Hosted Systems Builder
Hi, I'm Jarian.
I build secure things people can trust.
9 years in security engineering at Microsoft — M365 identity protection for 2.5M+ managed machines, FedRAMP / SOC 2 / BCDR / ITAR compliance programs, RDP modernization at ~3M-machine scale. Now I design security infrastructure, AI tooling, and self-hosted systems end to end.
