Johannes Winkelmann - Bio
Born in Switzerland, I’ve been in San Francisco, California for a few years now. In my spare time, I enjoy taking pictures, playing ice hockey, and spending time with my wife and our awesome cat Charlie.
I work as a Technology Evangelist for Sensirion, a sensor manufacturer building environmental sensors to measure humidity, temperature, air quality, differential pressure and air and liquid flow rates. As part of this role, I started our SF/Silicon Valley office, manage relationships with platform partners and represent the company at trade shows and conferences. I also get to give talks on our technology at events. Most recently, I was in charge of creating our developer portal at http://developer.sensirion.com, and provided tutorials and sample code for it.
Before that, I was the first software engineer on Sensirion’s mobile team, and was involved in supporting a very large Korea mobile phone OEM in integrating our sensor technology. I also wrote the Linux driver for the SHTC1/SHTW2 humidity temperature sensors which has since been merged to the upstream Linux kernel.
Before joining Sensirion, I worked at a home automation startup in Switzerland called Digitalstrom where I was working on the embedded server component, an embedded linux system. I also represented the company at their Developer Days, presenting our technology to customers and users.
Prior to that, I worked in a internet radio and networked audio startup called BridgeCo which was acquired by SMSC, which got bought by Microchip. I was working on making our soundcards compatible with the USB Audio 2.0 class as well as writing Linux kernel drivers for BridgeCo’s fourth generation internet radio platform.
Before joining BridgeCo, I was a research assistant at the Wearable Computing Lab at ETH Zurich, and also a research assistant at the Institute of Social and Preventive Medicine.
