Stop Guessing. Start Optimizing.
If you're a JavaScript developer working with PostgreSQL and tired of slow queries killing your app's performance, this course is for you.
What You'll Master
6 Modules. 15 Lessons. Zero fluff.
PostgreSQL Internals — Understand how PG actually executes your queries, MVCC, vacuum, and the buffer cache
EXPLAIN ANALYZE — Read execution plans like a pro. Spot the difference between estimated and actual costs.
Indexing Strategies — B-Tree, GIN, GiST — know which index to use and when. Plus the anti-patterns killing your performance.
Query Patterns — JOIN optimization, CTEs vs subqueries, window functions, and pagination that doesn't collapse at scale
Production Architecture — Connection pooling with PgBouncer, table partitioning, and continuous monitoring
Real-World Case Studies — E-commerce search optimization, solving N+1 queries in Node.js, and a final assessment
