Databases for Engineers
You write CRUD all day and the rest of the database feels like trivia. Learn indexes, transactions, joins, and normalization for real, so the database stops being something you fear.
Postgres Deep Dive
You use Postgres every day and your knowledge stops at SELECT. Go deep on MVCC, query planning, partitioning, and extensions, so Postgres becomes leverage instead of a black box.
Database Internals
Your queries are slow and the docs assume you know what an LSM tree is. Learn B-trees, LSM trees, and write-ahead logs, so the storage layer stops being magic underneath your code.
Query Optimization
Your slowest query is taking down production at 9am. Learn to read EXPLAIN, design indexes that work, and rewrite the queries that crush your database before they crush you.
Schema Design That Scales
You designed a schema two years ago and now every migration is a war. Learn the normalization, denormalization, and evolution patterns that produce schemas you can actually live with.
