Learn SQL, performance, and data modeling with real-world techniques — not theory
This is a pre-sale: modules are available now (slides, labs,
quizzes),
with new content added regularly. Videos will be
introduced progressively.
If you're comfortable learning from structured material and hands-on
practice,
this is the best way to get in early at a reduced
price.
From solid foundations to system design. Choose the level that matches your goals — Core, Advanced, or Architect. Each tier builds on the previous one, adding deeper capabilities and modules.

Learn PostgreSQL the right way
Build a solid foundation in PostgreSQL by learning how to think in SQL, not just write it. This tier focuses on clarity, correctness, and essential patterns that make your queries easier to read, maintain, and extend.
You'll learn how to structure queries properly, use advanced SQL features with confidence, and avoid common pitfalls. This is the level where SQL stops being a tool and becomes a language you can rely on.

Understand performance and execution
Go beyond writing correct SQL and learn how PostgreSQL actually executes your queries. This tier focuses on performance: reading query plans, understanding the optimizer, and identifying bottlenecks.
You'll develop a systematic approach to making queries faster and more predictable. Instead of guessing, you'll understand why a query is slow and how to fix it using proven techniques.

Design systems that scale
At this level, PostgreSQL becomes part of your system design, not just a database. You'll learn how to model data, structure queries, and make architectural decisions that impact performance and scalability.
This tier focuses on trade-offs: when to denormalize, how to design for real workloads, and how to balance complexity, performance, and maintainability. It's about making decisions you can justify in production.

Developers and database administrators who want to master PostgreSQL. Whether you're building new applications or optimizing existing systems, this course gives you the practical skills that matter.
Most courses teach SQL syntax. This course teaches you to think in SQL, understand how PostgreSQL executes your queries, and write code that's both simpler and faster. It's the system I wish I'd had when I started.
Content will be released progressively over the next 3 months. Early access members get discounted pricing and direct input into the curriculum priorities.
