About the Author

Hi, I'm Phil Ripperger. I'm a husband and father, a technologist, and a software developer.

I've built and supported web applications in one form or another for the past ten years. On some, I’ve been the developer and maintainer, but the majority of the applications I've seen have been in the official role of support. During the last few years as a support engineer at Heroku, I've debugged or analyzed over five thousand different applications.

I have an expert understanding of how Heroku works as well as many thousands of near-daily interactions with Heroku customers and their applications. In short, I understand Heroku from the inside and out.

I enjoy helping developers make better use of Heroku. My goal in writing this guide is to help developers better understand and solve common issues their applications will encounter on Heroku.

If you'd like to contact me, I can be found on Twitter (@pdsphil).
