Designing invisible fortresses for a multi-cloud world.

Redesigned enterprise network perimeter from implicit trust to full micro-segmentation. Deployed identity-aware proxies, mTLS service mesh, and continuous validation across 600+ endpoints. Reduced lateral movement surface by 94%.

Secured converged IT/OT environment across hospital network. Isolated legacy medical devices using unidirectional gateways, deployed ICS-aware IDS (Dragos), and achieved HIPAA/NIST 800-82 compliance without disrupting clinical workflows.

Built end-to-end threat intelligence pipeline ingesting 40+ OSINT feeds. Automated CVE triage mapped to internal asset inventory (Palo Alto, Splunk stack). Reduced mean time to detect from 72h to under 4h.

Architected internal adversary simulation capability from scratch. Built isolated attack lab with full OWASP Top 10, AD exploitation, and C2 infrastructure. Delivered 12 purple team exercises with measurable control improvements.

Hardened multi-cloud environment (GCP + AWS) using CIS benchmarks, enforced least-privilege IAM, deployed CSPM tooling (Prisma Cloud), and built security-as-code pipeline for infrastructure drift detection.

Designed and automated 24 incident response playbooks in XSOAR. Reduced analyst decision fatigue, cut MTTR by 61%, and integrated with ticketing, SIEM, EDR, and communication channels for full-loop containment.
