Ian has been in the software development industry for over 25 years, with the last 14 in management. That includes a long stint in AWS EC2 and a shorter stint at a quant hedge fund Two Sigma. Up until recently, he served as SVP of Core Engineering at Datadog, managing about half the engineering org that built the company's core data and platform systems. Ian is now enjoying his post-Datadog days and working on a new book about platform engineering.
