The short version

A developer at heart, an analyst by trade.

I started in telecom back when video calling meant 3G handsets and dropped sessions were a normal part of the demo. Two decades later, I am still in real-time communications. The stack is open now, the browsers ship it, and the hard problems have moved up the layer cake.

I co-founded testRTC and spent years building the test and monitoring tools that engineering teams rely on to ship voice and video at scale. After the acquisition I went independent. I write the BlogGeek.me blog, run the WebRTC Insights newsletter, teach the WebRTC Courses, and consult for product and engineering teams shipping real-time communication at scale.

What drives the work today is the same thing that drove it in 2012: real-time communications is harder than most teams expect, the vendor landscape is louder than it is honest, and somebody has to read the spec. I am that somebody. MSc in Computer Science, MBA, and a long memory.
