Hi 👋

I’m Andrew, and I’d love to help you with your PostgreSQL 🐘 databases and Ruby on Rails 💎 web applications.

Why work with me?

I’ve optimized multi-terabyte PostgreSQL databases running thousands of queries per second. I understand the kinds of challenges faced at that scale.

I love working with teams and providing educational material. I wrote a bestselling book High Performance PostgreSQL for Rails, published by Pragmatic Programmers in 2024, to help more engineers acquire these skills.

What will we work on?

📊 We can improve query performance, helping avoid unnecessary spending on larger instances
💾 Let’s optimize the schema design, queries, and indexes, for greater reliability and performance
🐘 I’ll perform data migrations for primary key conversions or partitioned table migrations, based on a plan we’ll review together in advance
👨 As a conference presenter and educator, I’m ready to train your team on PostgreSQL and Active Record topics. We can use existing materials or create a custom plan.

I’m looking forward to working with you!


What are off-the-shelf trainings?

Currently I’ve got Indexing Like a Pro Part I and Part II, ready to deliver as a live session with slides and live coding for your team. Each part is one hour, plus an optional Q&A.

How do I charge?

I offer a flexible structure based on competitive rates.

Tools and systems we'll use
  • I’ll need access to your databases or database observability tools (PgHero, PgAnalyze, Performance Insights, etc.). For databases, we can use a non-production instance or a read-replica, depending on your goals.
  • For code contributions, I’ll need access to your repositories, CI/CD system, and application observability tools (APM, exception tracking)
How I Work
  • I’ll provide a Independent Consulting Agreement
  • We can use Google Hangouts, Zoom, Tuple, or similar programs for synchronous calls
  • We can use Slack, email, and Google Docs for async work and statuses
  • I’ll track detailed time and provide regular invoices
