How to Use This Playbook

Use the playbook like an engineering program, not a book.

Operating model​

  1. Read the overview page for a layer.
  2. Implement the small examples.
  3. Complete the mini exercise.
  4. Build the layer project.
  5. Publish the repo, screenshots, architecture, and write-up.

Weekly rhythm​

  • Day 1: concept pass and diagram review
  • Day 2: TypeScript implementation
  • Day 3: Python implementation or backend variation
  • Day 4: exercise and extension work
  • Day 5: project milestone and documentation

How to get portfolio value​

  • treat every project as a standalone repo or documented subproject
  • add screenshots, API examples, Mermaid diagrams, and metrics
  • write one short engineering note per layer
  • record a two to five minute demo for each major project

Suggested learning path​

  • If you are new to LLM applications, start at Layer 1 and move sequentially.
  • If you already build LLM apps, start at Layer 3 or Layer 4 and come back to fill gaps.
  • If your goal is consulting or internal platform work, prioritize Layers 2, 4, 6, and 7.
  • If your goal is product or startup work, prioritize Layers 1, 3, 5, and 8.
