documentation and communication

focus on architecture documentation, storytelling for system design, reproducibility, data contracts, and whiteboard explanation practice.

key concepts

  • architecture diagrams (excalidraw, mermaid)
  • project storytelling pattern: what → how → why → tradeoffs
  • data contracts and schema registry
  • reproducible notebooks (jupyter, papermill)
  • live whiteboard practice for interviews
  • explanation of pipelines to non-technical and technical audiences

explanation practice

  • draw end-to-end architecture on digital pad
  • flow diagrams for pipelines
  • whiteboard explanation of ETL, streaming, or web3 pipelines

projects

1. project documentation repo

  • markdown + mermaid diagrams for each pipeline/project

2. data contract generator

  • schema registry integration for multiple pipelines

3. jupyter pipeline demo

  • automate data prep + ETL + feature extraction for ML

4. whiteboard interview exercises

  • recreate pipeline diagrams and explain in 5 mins
  • record self explanation for refinement
