Prompt Engineering for Practitioners
Beyond LinkedIn tips. Structured prompting, few-shot, JSON output, tool use, and how to ship reliable prompts that don't silently regress.
Building Production AI Apps with RAG
APIs, vector databases, chunking strategies, agents — the moment AI goes from toy to production. Includes Slack-bot RAG architecture.
Cloud IAM — Where Most Breaches Live
Wildcard permissions, iam:PassRole privesc, cross-account trust, Pacu, PMapper. IAM is the hardest part of cloud security.
Metadata Endpoints — Still the Killer Chain

AD Enumeration — Seeing Everything
BloodHound, SharpHound, Impacket, CrackMapExec, PowerView. Any authenticated user sees the whole directory.
