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.
Fine-tuning & Custom Models
When APIs aren't enough — train, evaluate, deploy custom models on your own infra. LoRA, vLLM, evals, and the cost trade-offs.
AI Security & Red Teaming
Attack and defend AI systems — the field almost no one teaches. OWASP LLM Top 10, prompt injection, jailbreaks, guardrails, RAG poisoning, model extraction.
Multi-Cloud — The Complexity Tax
Per-cloud skill, divergent defaults, N × CSPM. Multi-cloud without investment = weaker overall security.
The Shared Responsibility Illusion
Cloud providers secure infrastructure; customers secure configuration. Every breach happens on customer side.
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
169.254.169.254, Capital One, IMDSv1 vs v2, container metadata, K8s service accounts. SSRF → cloud takeover.
Cross-Account Trust Attacks
Overly broad Principal, confused deputy, External ID, Azure Lighthouse. MSSP compromise cascades.
Kubernetes — The Platform That Multiplies Attack Surface
Pod → node → cluster, service account tokens, RBAC paths, exposed kubelet/etcd. kube-hunter, peirates.
Serverless — New Surface, Not Smaller Surface
Lambda role credential theft, event source injection, dep vulns, supply chain. Serverless shifts attack surface.
