John Arundel

Hi, I’m John Arundel, programming mentor and author of various books on software engineering and tech careers. I’ve been writing software for about 40 years, and I think I’m starting to figure out how to do it.

I’ve trained developers and teams at Google, VMware, GitHub, HashiCorp, Pivotal, Gruntwork, Nginx, JPMorgan Chase, Facebook, Elastic, Grafana Labs, GoCardless, Cisco, Pythian, Intuit, and dozens of other successful companies (maybe yours, too).

Read on to find out more about my books, mentoring, training, and other offerings.
