Where capability becomes a shippable service.
A self-built, CLI-first course OS. 14 hands-on, project-based courses across security, AI, web, automation, and business — each one a real build, not a pile of notes.

Every layer GMTek builds on — taught as a build.
Security
Break it, then bulletproof it — authorized, lab-only, ethics-first.
AI
Ship AI features that are correct, observable, and cost-bounded.
Web / Product
Fast, distinct, production web — from the edge to the app layer.
Automation
Turn a real process into a workflow that survives production.
Business
Turn capability into a running, profitable consultancy.
Meta
Master the tool that builds everything else.
One proven shape. Every course.
Each course is its own repo with the same skeleton — so the discipline compounds instead of starting over. The point isn’t notes; it’s a measurable delta at the end of every phase.
- roadmap/ A 6-phase curriculum, fundamentals → capstone.
- coverage A living tracker — what’s done, what’s next, measured.
- builds Hands-on artifacts, not just reading. Real over fake.
- capstone A graduation deliverable that proves the skill.
- reuse Patterns and evals that feed the next course — and real work.

CLI-First Ethical Security Engineering
A legal, ethical, CLI-first path toward becoming an AI-assisted defensive security engineer — authorized labs only. Build detections, review code, harden systems, and automate forensics.
AI / Agent Security — Red Team & Hardening
Learn to break and bulletproof AI agents through ethical, authorized red-teaming — then build the guardrails and evals that keep them defensible.
Cloud & Container Security
Harden the cloud, edge, and container platform your apps actually run on — VPS hosts, Docker workloads, the CDN edge, secrets and IaC — and prove it with measured posture.
SIEM & Threat Hunting
Turn detection from a one-off skill into a monitoring discipline — and a product. Ingest logs, engineer detections at scale, map coverage to MITRE ATT&CK, hunt, triage, and alert.
DFIR & Digital Forensics
Investigate to an expert-grade, defensible standard — acquire and preserve evidence, analyze disk, memory, log and network, build timelines, triage malware in isolation, and write findings that hold up.
Offensive Security / Pentest Methodology
Structured, authorized penetration testing — the methodology, evidence discipline, and client-grade reporting needed to scope and deliver formal engagements.
An experiment in deep, sustained human↔CLI collaboration — building real systems, courses, and a business, one terminal session at a time.
