Most tutorials teach you how to build a "Hello World" app.
But how do you actually build, scale, and optimize a full-stack application for production?

I’m thrilled to announce the launch of my new Academy—a dedicated learning hub for serious backend and full-stack engineers.

I’ve launched with 4 comprehensive, deep-dive courses:

🐘 PostgreSQL In-Depth MVCC, WAL, Autovacuum, & Query Planning.
