Top SchoolIan Hollier is a Principal Software Engineer with a 35+ year career shaping consumer and cloud platforms, most recently leading Azure IoT efforts at Microsoft and now at Twilio. Raised amid the UK personal-computer boom, he blends deep systems architecture and product instincts with hands-on firmware and cloud integration experience, having helped found Azure IoT Central and shipped features across Windows, Visual Studio help systems, and early internet bill-pay services.

A seasoned mentor and team builder, Ian favors pragmatic experimentation—running small incubation teams to validate features before scaling them—and values creating a collaborative, family-like engineering culture.
