Z$ Learning Hub

Welcome—this is my working notebook for patterns I reuse: data wrangling, finance ops, docs, and creative tooling.

Goal

Ship copy-paste-ready building blocks with brief rationale and sane defaults.

What’s inside

• Pandas I/O Cheats – fast patterns for CSV/Excel/Parquet, types, and perf.
• Mermaid → PNG – export diagrams for decks or SOPs without local tooling.
• Snippets (SQL/Python) – ready to drop into day-to-day work.

Have an idea? Open an issue with the label proposal.
