Rafael Martinez

Cloud Security Engineer | Building AI Security Tools & Shipping Cybersecurity Products

I build security tools that solve real problems — from LLM security proxies to AI threat modeling to secure cloud infrastructure. Creator of Terminals and Coffee, where I ship cybersecurity guides and courses on Gumroad.

What I'm Building

Project What It Does
AWS DevOps Portfolio Production-grade AWS projects — ECS Fargate, EKS, ArgoCD, Aurora migrations, self-healing Lambda. Terraform + GitHub Actions + Well-Architected Framework
AI Security Architecture Practical guide to securing LLM-powered systems — threat landscape, attack techniques, secure design patterns, and reference architectures
OpenClaw Deploy Zero Trust Zero-trust AI workspace on AWS — hardened EC2 via Terraform, Tailscale mesh, Secrets Manager, IMDSv2, auditd, fail2ban
Cloud Automation Projects Multi-cloud automation scripts in Python, PowerShell, and Bash — AWS EC2/S3/IAM, Windows Server management, Linux ops
Security Architecture Fundamentals Practical security architecture reference — cloud design patterns, threat modeling, risk assessment, and framework mappings (NIST, CIS, MITRE)
Detection Engineering Lab Hands-on detection-as-code lab — Wazuh SIEM rules with MITRE ATT&CK mappings, Terraform-deployed infra, threat emulation coverage

Tech Stack

Languages: Python, Bash, PowerShell, HCL

Cloud & Infra: AWS (Lambda, API Gateway, Bedrock, DynamoDB, CloudWatch), Terraform, GitHub Actions CI/CD

Security: LLM threat modeling, prompt injection detection, PII scanning, SIEM/detection engineering, network traffic analysis
