“Leitz collected a few exciting problem/solution pairs that can significantly boost your productivity”
The 10 software rules I learned the hard way.
25 years of shipping production software, boiled down to 10 short rules. Read them over lunch. Free.
“10 Rules for Devs” is a short book. It covers the 10 most valuable rules I know for building business software.
I wrote it because nobody else was talking about these topics. Everybody learns them eventually. Usually the expensive way.
These rules came the hard way. Not from a professor in a stuffy classroom. From the trenches, writing real software that makes real money.
These are the 10 most important lessons I learned in 25 years of shipping systems that handle 100,000,000+ transactions a day.
- The importance of using custom scripts
- Question everyone
- Understand your tools
- The truth behind floating point numbers
Each rule is short. You can read all 10 in about 15 minutes and use them on Monday.

Mike Leitz. I wrote 10 Rules for Devs.
I've been developing professional, large scale applications for 25 years. Systems that handle 100,000,000+ transactions a day and generate millions of dollars for big businesses.
I also build and run my own production systems. About 50 apps on a homelab in my office. Java and Quarkus most days, with Postgres underneath. My main project is easy-easy speakeasy, a private club for developers who build and ship. You get in by solving a puzzle over SSH.
When you develop software professionally, you don't have time for big training manuals and courses. That's why I wrote 10 Rules for Devs. Read it over your lunch break.
