Welcome to QueryForge, Engineer.


You just made one of the best investments in your career. Here's exactly how to get maximum value from day one.


šŸ“š The Course (6 Modules, 18 Lessons)

Work through the modules sequentially — each one builds on the last:


Module

Focus

Key Outcome

1

SQL Performance Fundamentals

Read execution plans like a senior DBA

2

Advanced Query Optimization

Turn 30s queries into 30ms queries

3

Indexing Strategies

Know exactly which index type to use and why

4

GitHub Actions Foundations

Build production-grade CI workflows

5

CI/CD for Database Changes

Automated migration testing in CI

6

Production Deployment & Monitoring

Zero-downtime deploys with rollback


šŸ’¬ Community Chat

Ask questions, share wins, post your EXPLAIN ANALYZE outputs. I'm in there daily answering questions and reviewing query plans.


šŸ“‹ Updates & Resources

Check the Updates feed for new templates, cheat sheets, workflow configs, and announcements.


⚔ Your First Action Item

Open Module 1 → Lesson 1: How Databases Execute Your Queries and run your first EXPLAIN ANALYZE. Post the output in community chat. Let's see what you're working with.


No fluff. No filler. Just the skills that get you promoted.

Why Your Queries Are Slow (And Your Deploys Are Scary)

Most backend engineers hit the same wall around year 3-4:


  • Queries that worked fine at 10K rows now timeout at 10M

  • You CREATE INDEX on everything and pray

  • Deployments are a Friday-afternoon anxiety attack

  • Database migrations are "run it and hope nothing breaks"


Sound familiar?


I spent 12 years as a database performance engineer. I've optimized queries for systems handling billions of rows. I've built CI/CD pipelines that deploy database changes with zero downtime across dozens of services.


Here's what I learned: the gap between "it works" and "it works at scale" is a specific set of skills that nobody teaches.


What I cover inside SQL Performance & CI/CD Mastery:


šŸ” Reading execution plans like a senior DBA — not just EXPLAIN, but EXPLAIN (ANALYZE, BUFFERS, FORMAT JSON)


⚔ Query rewriting patterns that turn 30-second queries into 30-millisecond queries — CTEs, materialized views, partition pruning


šŸ—‚ļø Indexing strategies beyond the basics — when to use GIN vs GiST, how composite index column order matters, covering indexes that eliminate table lookups


šŸ”§ GitHub Actions pipelines that test your migrations against production-like data before they touch prod


šŸš€ Zero-downtime deployments using blue-green strategies with automated rollback


Who this is for:

Backend, DevOps, and full-stack engineers with 2-8 years of experience who are ready to stop guessing and start engineering.


$290/month — includes the full course, community access, and direct coaching.


The engineers who invest in these skills are the ones who get promoted to senior and staff roles. The ones who don't keep firefighting the same problems.


Your call.
