Hi. I’m Doug Sillars, and I help companies build mobile applications and websites that are fast, use less data, and don’t kill their customer’s battery.

I lead a team at AT&T, where we have created 2 innovative tools: Application Resource Optimizer  (ARO), a free tool that pinpoints network connectivity issues on mobile devices, and Video Optimizer, a tool that extends ARO into video performance analysis.

My primary roles are: outreach (presenting performance findings and helping teams improve their apps), research (studying ways to improve performance), and pushing the research into user stories that improve our tools.

I love writing, and blog regularly at the AT&T Developer website, where I create tutorials and videos.  I have also written a book:
