SQL foundations
Select, filter, sort, join, group, and explain queries in plain language.
Analytical lab
Data
A learning space for SQL, Python, practice notes, and small analytical artifacts that show how I am building data fluency.
Roadmap
Learning roadmap
The goal is not to collect random tutorials. The goal is to build a visible sequence from foundations to useful analysis.
Python for analysis
Clean small datasets, inspect columns, summarize patterns, and document decisions.
Mini dashboards
Turn practice data into compact metric cards, tables, and short takeaways.
Project writeups
Publish what changed, what the data showed, and what I would improve next.
Current practice board
Primary focus
SQL joins
Next skill
Pandas cleanup
Output style
Short notes
Project target
Mini dashboard
Practice notes
Join patterns
Examples for inner joins, left joins, and how to explain why rows appear or disappear.
Cleaning checklist
A repeatable Python checklist for missing values, column names, duplicated rows, and type conversion.
Insight habit
Every exercise should end with one sentence: what changed, what surprised me, and what to inspect next.
Next data artifact
Add one small project that starts with a question, shows the query or notebook, and ends with a short takeaway.
