Hi, I’m George Liu. I write about using AI to build practical web apps, developer workflows, and infrastructure tools.

I’m the developer and maintainer of Centmin Mod, a shell-based LEMP stack installer and management system I’ve built over the past 16 years for Nginx, PHP-FPM, MariaDB, and Linux-based web server environments. That long-term work in web stack tooling, automation, and production infrastructure shapes how I approach AI today: practical, technical, and focused on what actually works.

This Substack is where I share my AI builder journey, what I’m learning, the tools I’m using, and the apps and workflows I’m creating for my own use, including projects related to Centmin Mod and developer tooling.

What to expect

• AI tools and workflows that improve real development work

• Build logs and case studies from the apps and tools I create

• Tutorials and walkthroughs for AI-assisted development

• Reviews and opinions on AI products, coding tools, and builder workflows

• Practical examples of AI applied to web development and infrastructure
