Learning tracks
Data structures, async patterns, packaging, testing, and the parts of the language that trip engineers up at scale.
Prompt engineering, RAG, agents, tool use, and how to actually ship with AI in the loop — not just play with it.
SQL Server, PostgreSQL, Azure SQL, migrations, query patterns, and the behavior that only shows up under load.
What lands in your inbox
Mechanics, trade-offs, failure modes, and when to reach for something else.
Applied prompts that test judgment, not trivia.
The newsletter is the first step toward personalized drills and games.
