Start Here

If you only have a few minutes:
1. Capstone: CAPSTONE.md — design → deploy → monitor → respond
2. Featured Projects: 01_projects — production-style builds + docs
3. Detections & Runbooks: 03_detection + 04_runbooks — operational security maturity

---

What I Build (Capabilities)

Secure cloud infrastructure using IaC (Terraform modules, en layouts, secure defaults)

Identity-first security: least pri IAM, federation patterns, access reviews, break-glass workflows

Cloud telemetry and defense: logging, detection logic, tuning notes, and incident response runbooks

Hardening and operations: Linux baselines, service segmentation, backups/DR procedures, postmortems

---

Capstone (End-to-End Cloud Security Build)

A complete build with reproducible artifacts.

O: CAPSTONE.md

Architecture: Diagrams

Threat Model: DFDs + risks *(or link to your threat-model doc if you have one)*

Infrastructure-as-Code: Terraform

CI Security Gates: Pipelines *(SAST, dependency, IaC, container scan)*

Detections: Rules + test events

IR Runbooks: Playbooks + tabletop

E: Sanitized
