Get on the bench.
Do your reps.
Flashcards, in-browser coding, break-fix labs, and full-length practice exams — for Kubernetes, Python, economics, and more. Pick a subject and start your reps.
Reps work better when your method does.
Before the flashcards and labs, learn howto learn — a focus-first, evidence-based method: deep work, spaced repetition, active recall, and how to actually make hard material stick. Plus a curated reading list of the books it's built on.
Subjects
// grouped by area — each subject is its own spaceKubernetes & Containers
Master Kubernetes for the CKA — hands-on Learn + Break-fix labs, domain-weighted decks, a kubectl-speed drill, a recall exam, and Docker fundamentals.
AI & GPU Infrastructure
Run the infrastructure behind AI — NVIDIA cert prep, MLOps, GPU job scheduling with Slurm, and the datacenter operations behind model training and inference.
DevOps & SRE
Site reliability & DevOps — start with the beginner Linux Fundamentals on-ramp, then the LFCS Linux sysadmin cert and the HashiCorp Terraform Associate (003) infrastructure-as-code cert, each with objective-weighted decks and a recall exam, plus hands-on Linux & Bash labs, CI/CD, networking, and production break-fix troubleshooting.
Programming
Write code and master the tooling — foundational Bash, JavaScript & PowerShell decks, Python/JavaScript/TypeScript & SQL coding drills, the PCAP Python cert with a 150-question exam, and hands-on Linux, Bash & Git labs.
Cybersecurity
Break into security — CompTIA Security+ (SY0-701) domain-weighted decks, an acronym drill, and a full-length practice exam.
Configuration Languages
The config that runs modern infrastructure — write and fix real JSON, YAML, JSON Schema, Terraform HCL, and Azure Bicep in browser-graded drills, the traps included.
Secrets Management & DevSecOps
Handle secrets the way real DevSecOps teams do — Vault policies, Kubernetes Secrets & Sealed Secrets, SOPS/age encryption, KMS envelope encryption, rotation, and secret-scanning — with browser-graded drills (reusing the HCL & YAML parsers) plus focused flashcard decks.
Cross-Domain & Regulated Cloud
The cleared-world cloud skill set — DoD Impact Levels & data classification, Cross-Domain Solutions (guards, data diodes), FedRAMP / DoD SRG / RMF & ATO, and government cloud (AWS GovCloud, Secret/Top-Secret regions). Concept decks + a practice exam + browser-graded AWS policy-guardrail drills.
Model Context Protocol (MCP)
The open standard that connects AI apps to tools and data — hosts/clients/servers over JSON-RPC, the server primitives (tools, resources, prompts) and client primitives (sampling, roots, elicitation, tasks), transports (stdio & Streamable HTTP), the initialize lifecycle, OAuth 2.1 auth, and security. Concept decks + a practice exam + browser-graded config & message drills.
AI Engineering — SDLC, Agents & MCP
How AI systems actually get built and operated: the AI-native SDLC, agent harness engineering, and the Model Context Protocol that wires agents to tools. Agent = Model + Harness, and the harness is roughly 90% of the system — so most agent failures are configuration failures, not model limitations. Decks for the concepts, browser drills for the real JSON, and labs that need no API key and no real model.
Microsoft Azure
Azure administration & cert prep — AZ-104 decks, practice exams, and hands-on IaC/CLI/Azurite labs.
AWS
AWS ML & cloud cert prep — the AWS MLA-C01 (Machine Learning Engineer Associate) learning path: four domain-weighted SageMaker decks and an 89-question scenario practice exam.
Google Cloud
Google Cloud ML & cert prep — the Professional Machine Learning Engineer (PMLE) learning path: designing, deploying, and monitoring ML on Vertex AI. Blueprint, roadmap, and free-first resources are live; decks and a practice exam are in build.
Electronics & PCB Design
The hardware foundation - and the half of it that can actually be taught. Electronics fundamentals (Ohm's law, passives, semiconductors, power, grounding, test gear), soldering and surface-mount knowledge aimed at the IPC-A-610 body of knowledge, and tool-agnostic PCB design covering stackups, controlled impedance, design for manufacture and fabrication outputs. The hand skill only comes from practice; this is what makes that practice productive.
Additive Manufacturing & 3D Printing
3D printing as industry defines it, built against ISO/ASTM 52900 - the standard behind the SME Certified Additive Manufacturing Fundamentals (CAM-F) certification. All seven process families rather than just the desktop ones, plus materials, designing a part so it can actually be made, post-processing, quality control and safety.
Economics
Micro & macro fundamentals — supply/demand, elasticity, GDP, policy.
Marketing & Sales
Go-to-market for founders — positioning (Dunford), channels (Traction's Bullseye), discovery (The Mom Test), and selling (SPIN / Gap Selling). A nine-skill map with a lean reading order; decks and a scenario exam in build.
