Learn it by seeing it, then building it.
For software engineers moving into AI/ML, Claude-based agents, or cloud security — every concept is something you can click, drag and break.
No hand-waving, no walls of text. Pick where you're headed. 100% free, works offline, no trackers.
Q·Kᵀ → softmax → ·V, running live on five real 2-D toy vectors — the same three matrices every transformer runs at every layer.
AI/ML Engineer Roadmap
Zero → senior AI/ML engineer across 10 phases: Python, the math (as pictures), classic ML, deep learning, transformers, LLMs & RAG, MLOps, and agentic systems — design, train, deploy, operate.
Claude Certified Architect
Prep for Anthropic's CCAR-F exam: the agent loop, tool & MCP design, Claude Code workflows, prompt engineering and context management — all 5 domains as playable explainers.
Threat Modeling for Cloud
From developer to security contributor: the four questions, STRIDE, IAM and cloud controls on AWS, Azure and private cloud — mapped to CCSK v5 and SCS-C03, with a threat-modeling Studio and graded cases.
New here? The AI/ML roadmap assumes no prior ML. The Architect track assumes you already build with LLMs. Threat Modeling for Cloud assumes no security background, just working dev experience.
