PostgreSQL for Developers

YOUR INSTRUCTOR
Daniel Okafor
Daniel works on the layer where application code meets the database. He has spent years untangling type systems and query plans, usually in the same afternoon. He believes most runtime bugs are modelling mistakes that were visible earlier, and he teaches both TypeScript and Postgres from that angle.
View instructorWhat you'll learn
Write serious SQL
Joins, aggregates, CTEs, and window functions, without reaching for the ORM every time.
Design a schema that lasts
Normalise sensibly, use constraints as guarantees, and pick the right data types.
Make queries fast
Read a query plan and add the index that plan is asking for.
Operate it safely
Transactions, migrations, backups, and pooling — the parts that matter at 3am.
