Profile bio
About David St. John
I'm an unapologetic optimist and believe technology will save the world. I've been involved with several successful start-ups, starting with a venture formed during graduate school. I have strong expertise in hardware, software, team building and business development. As an avid wind & water sportsman, my passion around creating better weather data was born of a selfish desire to get more time on the water (saving the world is just a bonus).
Listed skills include Product Management, Software Development, Mysql, Remote Sensing, and 7 others.
